Hmm, the HTC ones looked really nice, I owned two or three of the high end ipaqs over a few years and yeah, I reinstalled the dang things many times. I loved them while I had them but now that I've had an iPhone I realize how crappy those things were.

That said, a CF and a SD slot in one device rocked and I just pulled out my Pocket PC and reinstalled it to use as a camera previewer, there's a program that will even handle RAW files. Feels like a POS in my hand though.
