It's all the megapixels ! - Mo Kargas

The last one I got (SD950) is just a bit too big for me, so I'm planning to get a smaller / less capable one the next time I buy a camera. - Amit Patel

do you like the sd950? i was thinking about buying it. - Jess Lee

The SD950 is fine except that it's slightly too big to fit comfortably into my pocket. I would've been better off with something smaller that I have with me all the time than with the SD950, which I mostly got for the larger sensor size. The one Paul's looking at (SD880) looks nice. - Amit Patel

The gold one (second from right) is an 880. So far, I think it's the best, though they just arrived today. - Paul Buchheit

The Olympus lines are getting smaller, and I love it. - Amit Morson

The 880 actually looks a little big as well. Might be a deal-breaker for me. But it's such a great camera otherwise. Sigh... - jakebf

The Canon IXUS 50 (aka SD400) was the perfect size... I replaced it with a IXUS 800 and always regretted it :( also, I wish the manufacturers would quit the megapixel race. 7.2mp (ie. 3000x2400) is more than enough ... I don't think I've ever needed to print an image larger than 10"x8" - Hobbsy
