Slimmer, non removable same size battery, super amoled screen, 1.2ghz cpu..... how ever, the reviews I have seen still seem to favor the bionic.... Alot of people seem to call the super amoled screen not good as it should be. From what I see, its still not as good as the Charge's either.
Another issue is you cant get an extended battery or pop in a replacement when getting low, get ready to carry one of those big 5000 mah external ones. lol
If the amoled screen is anything like the one on the droid charge it WILL use more power than the pentile. I foresee battery problems. with the DC the screen used 70+ % of the battery power. I am kinda curious to see how it all works out.
