zwei, there are videos you can look at on youtube (i did yesterday) and they had the Epic (it's called the Galaxy S or something like that -- Epic is just the name of the Sprint version) next to the HTC and another phone. they compare the screens across the board and the Epic does far better in the direct sunlight. plus, it's not just an amoled screen, but they say it's a "super amoled" screen . . . so there's that. ;~)

i did a quick search and here's a video showing a regular amoled screen, an LCD screen, and the super amoled screen to show you the difference; though, i didn't watch it, but the description implies the super is much better ("the Super AMOLED is definitely the most visible and beautiful").
