Ed Krimen from Photobird has taken a look at the 5 megapixel PoweRShot SD450 digicam from Canon, here's a small snip from his full review:

The Canon PowerShot SD450 is at the "sweet spot" of tiny digital cameras. I strongly believe that the minimum size for the LCD screen on any camera should be 2.5", which is what the SD450 has. Any smaller, and the screen is too hard to see. 5 megapixels is enough for almost everyone. You really only need more if you're a professional photographer, or if you have very specific needs. 3x optical zoom should be the minimum. More optical zoom would be nice, but I'd prefer to compromise on camera size, to have a tiny camera that I can easily take with me, than to have more zoom. There were times that I'd wish I had at least 5x zoom, but it was rare..
