Thanks both of you for the reply!
@jehane: I did spend 'some' time on the wiki page of all the readers put along side each other with their specs. I didn't get much from it, since it was obvious I was out of my depth.
I checked the forum, and came to the same conclusion as you poppaea. I think the Sony is the best choice. Shame about the availability of the pocketbooks! I would've snapped that right away. Although I was going for the 650 model, now that you mention the 950 and its wifi capabilities, I think I'll splash my cash on that one instead. Having said that, I haven't seen that model that often in shops. Hopefully I can get my hands on one tonight.
Cheers for the input guys. Very kind of you to share your knowledge. Will update this thread before or after I make a purchase.
