Welcome aboard, dfiler.
I've just got a new PRS-650 as well, and love it so far. I was very close to buying a K3 this Christmas, with the 6" Sonys seemingly sold out everywhere in the UK, but I found a unit that had been the shop demo device in a Waterstone's here a couple of days ago. It's the black 650 and once I got to play with it I knew it was what I wanted. The factors that swung it for me over the Kindle were the weight - this is the heaviest reader I've owned since previously I've had a Gen 3 and an Elonex 511EB, and yet the K3 would have been heavier still - and the library support.
However, now I've been using it I've also been very impressed by the PDF reflow, which works well for the two column PDFs I tend to read, and which by all accounts would not have been supported so well on the Kindle.
