Here is a sweet site. They have a ton of sample pics from every camera of the same things so you can compare them.

The only problem with the Sony is I don't think you can get 3 or 4 megapixel out of one. I liked the idea of a floppy for storage because it's so universal. But if you look at how many pics you can fit on a 64MB memory card, odds are you won't run out of memory.
My brother just bought one ( I think it's an Olympus ) anyway's you plug it into the USB port and internal software in the cam makes the computer recognize it as another drive so you don't have to worry about having special software.
You can also make quicktime movies on the Olympus.
