The main thing is not to be pursuaded to buy anything because of the amount of MegaPixels!
A good lens and sensor are are most important.
Nice to have at least 8 MP though, and a memory card to be able to store your pictures.
The internal memory, even on higher priced cameras, is usually very limited.
As Railrunner said, the Lumix is very good for daily use, but there are so many other options, and I can imagine everybody coming up with one...!
