The Kindle 3 Lighted Cover has quite an uneven light pattern. I was wondering how the PRS-650 cover compared - I have yet to see pictures of it in use.

The Kindle 3G/Wifi is a gift for my mother. It was a 'no-brainer' option for her because of the ease of purchasing books through Amazon, wirelessly.
I, however, don't mind plugging my ebook reader into a computer to update it.. so I am looking closely at the PRS-650.
I like the touch screen idea for looking up words in the dictionary.. also, I find the home screen superior to the kindle's.
I have to admit, I really enjoy the Kindle's wireless features, the side 'page turn' buttons for one handed operation, the physical keyboard -- so, in my mind, the Sony reader isn't a clear winner.
