Fuji have just brought out the Z2 - tiny little beast (90x55x18mm and 130 grams) with very quick start up and shot times plus it goes up to 1600ASA equivalent which would be very handy for low light situations.  Comet are listing it at £200 and seem to be the cheapest (Jessops are quoting £250).  It's not widely available yet thought so some dealers may start doing it for less.

For a pop in your pocket point and shoot I'd suggest it will take a lot of beating.

Alternatively the Ixus 55 is a nice little camera.
