I've just bought the Sony DSC-P72 and this case was included as part of a special offer. I'm very glad I didn't spend any money on it.Yes, it's very soft and good at protecting an otherwise un-cased camera, but why is the case so big? The main pocket for the camera actually has room for two P72s! I believe the main pocket could have been made a lot smaller and still be capable of storing any of the cameras listed.
Secondly, there are two main pockets in the case. The second of these has two inserts for storing batteries and memory sticks, but with only a thin mesh and a zip to separate them I wouldn't feel too safe carrying them both at the same time. If you're going to carry a memory stick in this case, you definitely need something else to protect the stick.
All in all, a suitable case for the camera (which needs protecting), but you don't get much for your money.
