Lumix FX-33 vs. Sony W90

[Perderte]

Well basically I'm looking to upgrade my Olympus MJU-Mini, to a more up-to-date model, with higher spec etc. My budget is £150-£200. I'm an art student and I take my camera everywhere with me, I don't use SLR's because I can get away with compacts and I find them a hassle to carry around, I'm basically just looking for something small I can keep in my pocket.
I use my camera for art projects and nights out etc. And I've narrowed my choices down to the Lumix FX-33 and the Sony W90, and I'm totally confused which one to get. If anyone out there has one and wants to give me some advice, or if you just want to express your view please reply

^^ I won't even consider it until you give me a decent reason to buy it. And besides I don't like those type of cameras.

I really need something ultra-compact that I can just keep in my pocket beside my phone or whatever. I take my camera on a lot of night outs (mostly clubs) and I need something that would work well in that situation.
I've found another couple that are in my budget and looks quite nice. Not only does the camera have to be good on the inside, but I like something I can flash at and people can look at (something sexy basically.)
I'm interested in the;
Lumix FX-33
Ricoh Caplio R7
Casio Exilim Zoom EX-Z1200
Canon Digital IXUS 950 IS

Anymore help on the matter is great thanks
