I'm in the process of replacing all my cameras over the next few months. As mentioned below, I've already added the 50D to my collection. I've also recently purchased the Canon G10 point and shoot digicam. I wanted a smallish p&s camera with good image quality (at low iso anyway) for those times a DSLR is too large to bother with. It will immediately become my skiing companion this winter. I plan to shoot some local Christmas festivals with it as well.
I must say, this is the best built p&s I've ever layed my hands on. Kudos to Canon for a great design. The image quality is exemplary as well at low iso (at least from the few test shots I've taken). This is definitely a major step up from my Canon S3 which it's replacing. I'm looking forward to playing with it a lot this winter.
Update - May 15, 2009: I thought I'd update my impressions on the G10's image quality now that I've had some time using it. My final conclusion is that it's far from revolutionary. While I appreciate the resolution that 14+ megapixels offer, the noise accompanying the camera is a bit annoying for me. I had hoped that the noise would be pretty minimal at iso 80 (the camera's base iso), but I've found that isn't the case. I think it would be acceptable for anyone who does minimal post processing work on it's files but my experience is that, even with a moderate amount of massaging (and I'm talking raw files here), the noise increases dramatically and needs to be dealt with. Please realize that I'm extremely picky when it comes to image quality (being spoiled with Canon's higher end DLSRs) so others may not agree with my whining! The bottom line is that, while I do consider the camera a big step up from my Canon S3, I'm still finding that I'll take it with me on midday scouting trips or skiing ventures, but little else. And, of course, any kind of action photography that would require sensitivities higher than iso 80 are out of the question.
