No touchscreen, no deal! Ever since I purchased my PRS-900 last January, I knew I would never buy another reader without a touchscreen. Now I also have the PRS-950 and loving it. My Kindle 2 has been on permanent loan to one of my nephews for 10 months now. I still purchase books from Amazon occasionally but have it sent to my K4PC and then I make a Sony copy!
I'm finding more stores are matching Amazon prices so if it's off by .50 cents or less, I buy the ePub version. A Year ago 70% of my purchases were from Amazon now about 20%!
