I've decided!
It's going to be a PRS 900.
It should help me to read any kind of documents any where, and two dictionaries should help me to a great deal! And then there's the note taking feature, which ofcourse will help me with many things. (I am hoping to see atleast a couple of replies now, it feels weird to reply to my own thread :P )
Anyway, this thread will help me fight the anxiety which I'll be facing till I have the device in my hands. And I think I feel like a father expecting a child (I just realized I am ridiculously silly!). And this child will be coming after crossing (flying probably) seven seas. Call me crazy but this is exciting for me.

Thank you Kenny and Mobileread and Maxbookworm and everybody else.
I will make more sensible posts here about why I chose the device, what are its capabilities (I know, PRS 900 has been out for a while, but still

), once I have the device with me.
