1. Pick a Tablet (I suggest notApple unless you need Apple for work... well, or if you are rich and don't mind being a wastrel.)
2. Make sure the tablet has the following things:
Mini-HDMI Out (For when you have access to a decent sized monitor.)
Ability to connect Bluetooth Keyboard and Mouse
Some kind of case that doubles as a stand
bigger bag to carry tablet and accessories
3. Suggest buying 16gb and rigging up personal server for external storage.
4. Buy the tablet
5. set up tablet screen with stand, connect bluetooth keyboard and mouse, BSSH to linux box. (Or remote desktop, depending).
6. Use use Lynx, IRC, Pine.
You are now the coolest kid on your block.
