FWIW, when I get another Digi I will look for the following:
Excellent closeup capability. Harder to find than one might think.
Better viewfinder..as mentioned above.
Less lag time
Higher OPTICAL zoom capability (NOT digital zoom)
Panoramic capability would be nice but not crucial
Notice I didn't say higher megapixel count. IMO, even 4-5 MP is overkill for most people. Unless you're doing very large prints or posters. My Sony camcorder (with still pic capabilty) is very light on megapixel count but utilizes 3 CCDs, not one as most camcorders or cameras. The color replication and saturation is unbelievably good. Superior to my high pixel count Digi Camera.
www.epinions.com is a great place to see feedback from product owners. Also,
www.slickdeals.net often has discount coupons and rebats for cameras and memory.
www.newegg.com and
www.ecost.com also have great prices.
Edit:
Add to my list, seamless video clips. My camera does an excellent job but is a bit glitchy. Perhaps a faster card or camera will solve this. I've seen flawless results with other cameras. Originally I didn't think I'd use this feature but I use it alot...easier than lugging a camcorder around. As storage cards get bigger this becomes more attractive. IMO Camera/Camcorders, using 100% solid-state tech, will be predominantly marketed as one product within the next couple of years. They're already here....
