I think the whole eten X800 running windows XP is only via remote desktop - which means that it's only able to display and remotely control some PC somewhere over the internet - which also means that XP isn't actually installed ON the eten X800.

I dun think the X800 spec can support XP altogether

Having 3/3.5 G DOES give u edge especially with a PDA phone as u can surf d net with it.

But personally, even with my Dopod 900, I rarely use 3/3.5G. Unless I'm stuck in a jam n I'm bored to death.

Design-wise, I like the x650 better.

Verdict, I'd go for d x650.
