I didn't realise there were comments at the bottom of the petalpixel page but sigh it appears I share some of the same concerns.
I really do want a panoramic digital camera though, perferably a swivel lens digital pano like the Widelux (although that's not likely to ever happen). A camera like this could very easily be my everyday carry.
Failing this, maybe the equivalent of a digital Xpan. I'd love this too but I imagine the cost of a camera like these would be prohibitive.
