I still love my kindle keyboard, but I would be very tempted to buy a PW if the memory was increased to 4 GB. I know we can keep everything on the Cloud, but I just don't want to. I know I can back everything up, but I just don't want to.
I have about 1.8 GB on my KK right now
ETA: I think I will also really miss the page turn buttons, but I suppose those are gone forever once they stop making the KK.
