My 10megapixel cannon powershot is all I need, and more.

I take a lot of macro/close up pics, and I find the max resolution is way too high to make it easy to edit pics on my comp. Really for most people 6 megapixel would be more than adequate.

Hell, if you're just going to upload your pics to facebook/the web anyway, 3-4 megapixel is probably fine.
