you can adjust the screen brightness which really helps when outdoors. I found my screen protector made the screen worse when outside too
(although ive only got the s2)
overall you cant compare the 2. The galaxy is a much better phone overall. I know your last android was cheap and nasty but when youve tried one with some decent hardware inside and on recent firmware you really wont be dissapointed. Trust me Paul, the apple has had its day!!!
