Ideal solution would be this (also less carrying stuff around)

- Nokia N800 and Nokia E70
- Same charger for both of those devices

So basicly the E70 would be used as a input device and a modem. E70 is a capable device but the screen is less than ideal. But I bet the E70 doesn't allow 2 simultaneus connections. Meanwhile someone should point out el cheapo keyboard to buy while figuring out something more practical.
