I have one, awesome camera for carrying around in your pocket. Unfortunately I lost mine in a little-used pocket for a couple months, and after searching everywhere, bought the new Sony DSC-P150 to replace it...most features are the same, but it's 7.2 megapixel, takes higher capacity memory cards, isn't quite as thin & compact, but has a better lens and zoom. Of course the week I got the new camera, I finally found my old one.

If I had to pick one, I'd pick the P150, though I prefer the T1 for pocketability.
