Me too. I had the 505, 300, 350, 900, and 950. But Sony's store deficiencies and lack of usable syncing between devices drove me to the Kindle. I also had and loved several Sony PDAs (Clie line) that ran the PalmOS. They were ahead of Palm in those days, but they withdrew from that market too.

I still think the PRS-950 was the best e-Ink reader I ever owned as it was perfect for reading in landscape mode. The front lit ereaders still look like crap to me, so I think Sony was right to give up after the PRS-700 fiasco.
