Olympus X-42 or Panasonic Lumix DMC FS42

[nep490]

I'm looking to replace my digital camera and have seen the Olympus X-42 and also the Panasonic Lumix DMC FS42 both in Argos. I haven't been able to find many reviews for either of these cameras and wondered if anyone could advise which one is best. The Olympus seems really good in comparison with the Panasonic value for money wise but the only issue I have is that the Olympus takes AA batteries and I had wanted to get away from that as my current camera eats batteries. I found one review which said you can take 150 photos off a set of batteries but I'm pretty skeptical because of my current camera. Any help or advice would be greatly appreciated! Thanks!
