Get one with an SD memory card.
Those are so cheap now, buying memory will be a pain with more expensive sony.
My friend is using the Casio exilim at the moment and they are jam packed full of features.
If I wasn't in digital SLRs I'd be going with one of those as well.
They keep putting out new models too, so the older models are cheaper too.
