What sort of computer / electronic device would you take on a backpack trip around Europe to allow you to keep in touch?

I think there are two views here.

Firstly, the backpacker as we know it is changing, or splitting. There are still the 'true', 'hardcore' backpackers, who want to hitchhike everywhere with two pairs of socks and three shirts and a sleeping roll on their back. That's great, but it's not for everyone.

As hostels become more ubiquitous, wifi appears compulsory, the new 'flashpacker' (look it up!) has appeared. The gadget conscious, connected budget traveller. I know I fit into this category, so I'll talk about that.

Throughout Europe, I took a netbook. The advantage of netbooks is the battery life - I'd even consider a second battery next time, just because I'm a geek and use it quite a bit. Wifi is in most hostels, or failing that, in streets. Netbooks don't garner that much attention, and you get used to pulling it out to use. They're also very light.

Now I know people may argue that iPads have longer battery life and are lighter. This is arguably true. However, they're still an attention-grabber, like it or not. And as a traveller, I dislike having unwanted extra attention to my gadgets. It may seem fine at home, but when you're in the middle of a dodgy street in La Paz, I'd far rather pull out my well-used and cheap netbook than a shiny expensive iPad ;)

I also have a smartphone, and the best use of that was for maps. Google Maps was near useless east of Europe, and you need to be online anyway. I downloaded NavDroyd, which cost a few dollars but has free regularly updated maps of EVERYWHERE, sourced from OpenStreetMaps.org. The interface was a bit fiddly, but it was a life-saver in places like Kyrgyzstan.

The other benefit of a netbook is Skype and communication tools. Yes you can Facetime on an iPad, but they've been shown to use quite a bit more data than necessary. I personally find the ability to use more than one program is also hugely beneficial - I can Skype and browse to links in my browser at the same time to send to the people I'm chatting, or look up maps to talk about, for example.

I used to have the original 9" Asus EEEPC 901. It was fantastic, loved the solid state drive and it weighed less than a kg. After two years of heavy, heavy use it finally had some SSD issues after a power surge in Chile. I now have the Asus R101 - a 10" as it's much harder to source 9" ones any more. It's still a fantastic PC, but if I could have gotten another 901 I would have. However I can surf, do video editing, chat, Skype, and watch tv on it with no problems, despite it being a low-power netbook.

I think you have to ask yourself two questions? How connected do you want to be and how much are you willing to carry.

• Unless you are doing heavy work, a laptop should not be an option, it is way too heavy.
• Do you write a lot? A travelog, long emails? - take a Netbook
• Do you always need to be connected? Do you plan to use Google maps to find your hotel when running around in a foreign city? - take a Smartphone. Want to read a lot or watch movies? - take the tablet.

My personal recommendation:

Take none of them!

I am very 'weight conscious' when I travel, so I try not to take too much electronics. Still I can't live without certain things, so I usually carry:

• A small iPod, shuffle or Nano.
• A good point and shoot camera.

• Two 1.8" USB hard drives, to store photos and additional music as well as some Virtual Machines just in case I have to work somewhere. The 1.8" ones are so much lighter than the usual 2.5"ers and they always work with a single USB cable for power. Of course you want to take two in case you lose one of them. Store them in different parts of you luggage.

• For my next trip I will also take the small Kindle, it will replace both paper novels and guide books. Many hostels now have free WiFi, so I can even use it go online if I really have to.

So, how do I stay connected? I usually stay in hostels and most of them have computers the guests can use for free. I haven't traveled much in Western Europe recently but free internet maybe not so widely available. Also there are less internet cafes these days than there use to be. So for Western Europe this may not be the best option.

To keep connection with home I don't use fancy gadgets that could get stolen. I prefer instead:

I recently traveled around Europe with the Samsung Galaxy S2 as my sole means of communication. This proved perfectly sufficient, and incredibly useful. As it is significantly smaller than a computer or tablet, it is easily transportable in a pocket. As a result, you can carry it with you at all times, even when walking 6+ hours a day as I did, without extra weight. Battery life easily lasts a day.
I would recommend the S2, as with the largest smartphone screen, it makes communication easier - more room to see, and to type.
It is also great as an e-reader, perfect for trains/planes.

For connectivity, free wifi spots are fantastic. I made extensive use of McDonalds wifi in several countries, sometimes just by standing outside.

Skype also works fantastically on this phone, and I used it several times to video phone with family.

In terms of backup, I believe that you can buy adapters to connect to external usb storage. And with 8GB+ internal storage, with sd card slot available, you should have plenty of room!

Another article on this from TooManyAdapters:

Staying in touch while on the road

It discusses getting a smart phone / device of some sort, teach friends/relatives how to use chat programs and VoIP programs like Skype, and buying local sim cards.

If you absolutely need to backup your photos, I'd go with a netbook + smartphone combo. Otherwise, you could get by with just a smartphone. It lets you access maps, app, and the internet. There are lot of offline mapping apps, like Galileo, which you can use to navigate around the city or country. What you do is load up the data while you're connected to wi-fi at your hotel, then you turn off data roaming when you're walking around the city.

For people who find surfing the net annoying on the smartphone, you could go with smartphone/tablet combo. If you have more money and are willing to take a risk, you could go with smartphone+Macbook Air.

Wi-fi is everywhere, and should be available in your hotel. Browse Tripadvisor or Hostelworld reviews to make sure other travellers also found the wi-fi to be good in your hotel. 3G coverage is also everywhere. If you need to use wi-fi while you're walking around, just look for the nearest Starbucks, which has free wi-fi. There are also a bunch of apps that download a database of all free wi-fi locations in your area.

If you're using maps and GPS a lot on your phone, it can drain your battery fast. I'd recommend bringing a recharger. On a recent trip, I carried around the New Trent IMP120D, which had 12000MAH or 6 iPhone charges. It was too bulky for a pants pocket, but since it was winter, I carried it in my coat. If it was summer, I'd probably go with a smaller device for day trips. 2000MAH equals one iPhone recharge, so anything that's 4000MAH+ would probably suit your needs. I never had to do more than 2 recharges during the day. Make sure you charge it up all the way at night. These devices are also convenient if you're staying at hostels. If you're sharing the room, you can lock up your iphone at night, and just leave the recharger in the wall socket. Most of these are under $80, so it's better to risk losing the recharger than your phone.

I'd recommend smartphone only for the following reasons. In my view the 2 disadvantages mentioned (not able to backup data; not as capable) largely don't matter.

• Less bulk in your backpack; less stuff to steal.
• A smartphone can do pretty much everything (general internet access, maps + gps, take decent quality photos, play music). Agreed, not as handy to use as a laptop if you need to book flights quickly or whatever, but there are computers widely available at hostels and internet cafes.
• For most people, the best backup option is the internet anyway; e.g. Dropbox or one of several other services. ^{(Assuming you have decent connectivity from time to time, but in Europe you generally have.)} You can perfectly well upload your photos etc from your smartphone. I'd argue that the storage on a computer you carry around on a long trip makes for a lousy backup strategy.

Yes, for games and movies, etc, a smartphone isn't optimal, but then, you can do all that at home. How about exploring Europe instead? ;) If you want to do things like video editing while on the road though, then yeah, take a netbook/laptop.

I have taken many trips around Europe (and the world) with this approach and never really missed a bigger computing device of my own.

General wifi availability varies a lot from country to country, but in good hostels and hotels you'll find it everywhere, so it should't be a problem. (Except for foursquare addicts like me :P). E.g. in Hamburg, Germany very few restaurants and cafes have wifi while in French or Italian cities it's much more common. Besides Starbucks and McDonald's, Apple Stores are good for wifi, and make for an internet cafe substitute too.

Small tip that I use all the time: load up maps of your next destination when you have wifi access (so that the map data gets cached); then when arriving there and looking for your hostel, etc, you can navigate perfectly with just the GPS signal (no costly internet access needed).

One factor you may want to keep in mind is electrical plugs.

With iProducts (including laptops), you can buy from your local Apple store a worldwide kit. This was useful when I was going from Australia to Japan in July, with an iPhone and a MacBook Pro.

By contrast, Asus' website makes it hard to get a power cord. I'll be going to Japan again in February, and taking an Asus notebook with me. Currently I'm planning on taking a "universal adaptor" with me, and possibly buying a power cord once I get there. I haven't been able to find in Australia an adaptor for Japan handling three prongs - maybe they're not legal.

I don't know how reliable a "universal adaptor" will be. When I was googling about using computers bought in Australia in Japan, I got conflicting advice about whether the lack of a third prong will be an issue. I'll try to add examples of websites giving conflicting advice some time this week.

From personal experience, I would recommend smartphone only, but with a power bank. Usually, I just travel around with my smartphone (Samsung Galaxy S4), with a 64GB Sandisk Ultra MicroSD Card. This can store thousands of photos. Also I have a Xiaomi Mi Power Bank(about 10400mah) which can be found for about £15 on eBay, shipped from China.

Both are very light, and the bank fits into the palm of my hand, and the standard Samsung charger is very compact too/ It charges my phone about 4 times, so I can go for about 4 days.

As the S4 is also an international phone, it will almost certainly work all over the world on multiple bands.

Also, you could download the TomTom Europe app from the play store. It is about $25 AFAIK, but it is completely offline, and all you need is a GPS signal, and it functions exactly like a TomTom device.

Also, if you like modding your phone, I have the Ultra Power Saving Mode from the S5 on my S4, and for one day of taking photos, while in Aeroplane mode. The only trade off is that you have a limited number of apps (so no Candy Crush!). I had 85% left at the end of the day, and about 75% without aeroplane mode and data disabled. Therefore, in theory, I could go for about 12-16 days without plugging in (4 days on phone battery * 4 charges = ~16 days). Of course, your mileage may vary.

The only trade off is that the bank takes about 10 hours to charge, and you can only charge one thing at a time with the S4 charger, so the charging time is about 12 hours in total (for the phone and the bank)
