The best 2mp Digi camera money can buy is the Canon A60, you really can't get much better at this range,
it's identical to the A70 in every respect except the megapixel difference and max video resolution.
Yep i have one, i went from a Sony 3.2mp to that 2.1 mp a60, much better cam.
Big Resolutions really means nothing unless you are gonna print over 10x8, so if you no intentions of going over that print size or ever printing them at all, stick with the lower MP cams, saves dosh!
The whole megapixel race is getting a joke, for the average person who wants to take some shots, print a few out around 6x4 threw to 10x8... those 6MP will probably never be needed. 2.1mp threw to 4mp should suffice.
Only thing i look forward to is possibly superior video handling, we have 640*480 25/30 fps Digi cams starting to show up already
Spend your money on what you need and can afford, there is more to the cams that just megapixels.
