I travel for months at a time.
A laptop is simply too big and heavy.
I used to travel with a Canon SX10. Now it is a tiny SONY camera with an underwater case.
I travel with an ereader. A KOBO touch. I read a lot on long trips and I can bring travel guides (Lonely Planet). Sure a tablet is nice but the screen for reading is much better on a Kobo touch. Sometimes I use my friends Samsung Galaxy Tab.
I wish the tablets had an eink display.
But the #1 device I travel with is an old Dell x51v. Now discontinued.
Great for email, internet, lists, contacts. Sure the tablets are made to replace this, but the Dell is ***MUCH*** smaller, works with both wireless and direct LAN cables, and has lots of software available, GPS too.
I do carry all software I use on a Kingston 32 GB thumb drive.
An LED flashlight is key.
A cell phone is very handy. Unlocked of course. I buy a SIM card in an y country I go to
So. Small and light with international capabilities. I use a dust and waterproof Samsung GT 82710. I once dropped a regular cell phone in an Asian toilet traveling from China to Mongolia.
Oh. Gomadic makes a single charger to charge everything so I do not need to have a charger for everything..
I realize that much of what I carry is old and different, but over years of travel, this is what I use.
