I have been shooting Nikon SLRs and DSLRs for the past 30 years. In the SLR arena, Nikon and Canon are usually your best bets. The Nikon D90 is incredibly sweet. I have one.
For small cameras, there are a few Nikon dogs out there, as much as I hate to say it. Panasonic and Canon are usually on top. One thing I like about the Panasonic is that they actually have wide-angle capability in their small cameras. This is a point that should not be discounted. Many camera buyers think that they want ZOOM (meaning, telephoto). 10X ZOOM, 12X, whoopie! The problem is, not very many interesting photos are taken at high levels of telephoto, unless you are shooting wildlife. You can't even hand-hold these small cameras at 400mm equivalent, f/6.3 or whatever... unless you are in very bright sunlight. Lots of telephoto makes for very FLAT images. Avoid that urge.
If you think you will take good photos of your kids sports events with these small cameras and oodles of zoom, please... trust me when I say that it's extremely difficult, and the small point and shoots just can't keep up with action.
If you learn to actually compose your photos, they will look so much more interesting. That is where you need wide-angle.
I actually DO NOT like P&S cameras that use AA batteries. The problem is, these batteries just don't have the juice to last very long. What happens is the marketing guys say that the engineers need to make the camera work with two AA batteries. The engineers comply, with a camera that lasts 30 or 40 shots with alkaline AA batteries. Rechargable batteries last even less. These cameras are finally starting to come out with their own dedicated lithium rechargable batteries. Use them. They work.
I have a Canon P&S A570, and the only batteries that last more than 10 minutes are non-rechargeable lithium. These run about $5 bucks for two. Sigh.
