Yes.
Seems to be decent enough for your purposes, as you don't want to go the SLR route.
What other ones should I be looking at ?
Panasonic FZ8 is cheaper and similarly good. The technology is sufficiently mature that you are unlikely to get a bad camera, if you buy a proper brand one.
Maybe Canon PowerShot S5 IS...
Is 10 Mpix an overkill ?
Yes and no. For most uses, 3 megapixel is more than sufficient, if supported by decent optics and low noise etc.
If buying new now, 6 megapixels should be the minimum, and higher is nicer. Don't choose a camera based on megapixels alone.
But if you will be wanting to print out at sufficient size for a lounge wall, go for as high is you can!
