Whats the best ultraportable digital camera?

I just bought my sweety, who rides a bicycle all the time, a Canon SD 700 IS. It is image stabilized, incredibly compact, has a 4X zoom, and has a chip so quiet that it can use ISO 800. Shoots AVI movies. Incredibly tiny camera and very high quality!

Downside? Does not do aperture priority or time priority. You can mess with the ISO to get a little of that. But when you are looking for something really ultraportable, you are not really looking to do high end SLR work, either.

Review below. Best of luck.

get a cellphone with a high resolution, at least 1.3 megapixel.

not the best quality. but definately "Ultraportable" because you always have it with you!!!

Casio makes excellent portable cameras, most can slide right into your shirt pocket!

The smallest I have seen so far is Sony Cybershot U. It is size of your thrumb. The new model even have flash.
