I gave up travelling with laptop,
What I did was buy good high speed external harddrive, which is in waterproof, drop proof case,
I installed portable desktop that allowed my to install my software on which allows me to run the programs from any computer (even without admin rights etc )
Now I just go to internet cafe, library, friends, or works computer plug in drive and run all my software from it. no records cookies, passwords are stored on host computer but as extra measure you can run use firefox portable from the drive.
With art/photo software I use GIMP and Inkscape, all open source that run from you external drive. I have an online storage account where I back everything up too.
I can run, open any microsoft documents etc,
Best bit is it all free, expect the actual externaldrive
I sort of agree, and disagree about the electronics in the wilds.
I think what you want to do is on to a loser, and that the above idea has more merits. I would be tempted to do it with a USB stick like this.
Kingston Micro Reader
4GB stick and you can add memory cards, so between your phone, and camera you should be able to play when you find a computer. Put potable apps on it, and you should have no big problems, but I would try it at as many places as possible, like a library.
This product fills me with hope, but only up to 2GB SD cards.
Ectaco Jetbook Mini. 90 hours from 4 batteries, add in a battery powered MP3 player, and your phone, and that set up could work.
Something like this to charge phone, and batteries.
Powertraveller Powermonkey-Explorer Best bit, you can charge its battery using USB, so when you editing etc, or uploading, change it. Would be tempted to have two batteries.
Androidgold's A2
This looks very interesting from a laptop point of view, but you never getting something with a lot of charge. Also would be nice to be able to carry a spare battery, but the above charger not a bad alternative.
Think that the big thing, if it runs on normal batteries, you can buy some if worse comes to worse.
I like the idea of being able to read, listen to music, and take pictures, not sure anything else is practical at moment. Would be nice to be able to journal as well but have to carry a notebook anyway. Also what else do you need to do?
