well i have the cannon A70 so i am biased LOL
the cannon A70 is very simialr to the A80 except for a few things.
A) the swivel LCD lens on the A80 is fantstic, i could have used this feature so many times.
B) the resolution is more in the A80 than the A70
thats basicly the difference i think.
if you want to see the quality of the A70 camera, then you would probably expect to see similar quality in the A80. i have a whole gallery of images taken by the A70 on my website, i have the shrunk down small versions and then the uncompressed full sized images. here is the link to the BIG ones, if you don't have the bandwidth just go down one gallery with the button in the top right side.

i really am pleased with the A70, i don't know about other cameras or more recent ones i got ine about 5 months ago.
also taking AA batteries is great
