For an ultra-compact with a wide angle lens, look at the Sony Cyber-shot
DSC-W170. This is presently the only sub-compact with a Li-Ion battery,
wide-angle lens, optical viewfinder, and image-stabilization. Alas, it's
$225 (US).

One issue with Sony: all their cameras are using the proprietary Memory
Stick, which is often not supported by build-in card readers in e.g.
laptops and other devices. Not a big problem, just something to be aware
of.
A friend of mine was pretty desparate when once he couldn't find the
download cable and couldn't get the old photos off the camera before
going on a long trip to NewYork..
