Sony F88, W1 or P100?

[luciana]

I'm willing to buy one these digicams from Sony: F88, W1 or P100. So, I'd like some advice on which one should I choose.
I've always used automatic cameras, so all the manual settings are not really necessary for me. It'll be used for family shootings, parties, holidays and so on. Therefore it's important that the camera has a good size and weight and it's easy to use.
Why Sony?
I'm Brazilian and here they're much easier to find and less expensive than the Canon cameras, for instance.
I've read most of the reviews on these cameras and seems to me that the differences among them is little, but I'd appreciate some opinions.
Here in Brazil, W1 and P100 are at the same price level and F88 is a bit more expensive. But if it's worth it, I would not mind paying it.
Thanks in advance for any advice.
