Actually, it’s 8mp. Though if I waited the XTi is 10.1mp. And the latest addition the XSi will be 12.1mp. Doh, if I only waited.
And in a few years.. even more megapixels..It is nice that the newer digitals are coming out with more for less… unlike many things in life. You just have to pick a point where the number of pictures you take will justify the cost. I did jump on a 12Megapixel DSLR recently, when it came out (SonyA700, body only – partially because it is compatible with my existing lenses(Minolta), and because of the build quality – enviro sealed with magnesium/aluminum alloy frame). At this point I’ll stand pat until the full-frame sensors come down in price.
