Canon Powershot SX10 IS or Nikon CoolPix P90?
oh yeah, SX10 hands down… only thing that bothers me about it are the AA batteries… everything else is top notch… when I bought my first camera, it was the Panasonic FZ-28… which is another alternative to the SX10… I believe it is as good as the SX10, I just valued the FZ-28′s features more than the SX10′s… so possibly look into that camera too…
read this review of the P90, it has side-by-side comparisons to the SX10, and you will see, SX10 is a clearly superior camera:

actually the P90 is a pretty awful camera if you ask me… I’d rather get the Fuji S1500 and save myself some $$…
