Iphone:
Scroll to the very top by tapping the top of the screen
Control media player from lock screen
dedicated ring silence / mute button (I can mute my iphone without pulling it out of my jeans pocket)
Just "plug and it gets synced and backed up" (no extra apps to do this let alone having to pay for one!)
having a few other languages for the keyboard without having to install a different (paid) keyboard.
The auto correct seems a bit more annoying on android
I like how on iphone when I type numbers, then press space, it automatically switches back to letters.
The camera on SGS2 doesnt seem to remember the settings, e.g. Auto Contrast keeps resetting to off. This probably has nothing to compare with iphone though but shows that SGS2 has lots of 'rough edges'
Double click on home button would be handier to go to phone I think - or at least make it customizable
One thing you must remember a vast majority of apps on Android are free. If your not a big app buyer (like myself), iOS, if anything, shouldn't suit you.
Most paid apps in Android Market get under 100 downloads - Phone Arena
Have a read. On the Market, the demand for paid apps simply isn't there, so developers make them free - This ties in with the fact you have to pay a couple of hundred pounds (or a 100, or something similar) to be a DEV for iOS whereas, I believe, it's free for Android, so there's less of a need for DEVs to charge to make their money back. I actually found, the 5-6 apps I've bought for my HTC Desire, at least 2-3 have now gone to waste because my GSII has built them in.
For syncing, there's doubletwist, that's free and should auto sync. AirSync is a paid add-on to do that over Wifi.
Controlling from the lock screen, my GSII does that, stock I think. Slides down on lock screen from the top.
Dedicated button - when not in a media app or game, hold down the "reduce volume key" and it'll adjust the volume, and keep reducing until it goes down to Vibrate profile - but still you have to turn it on, so it may defeat the object for you.
Have a play around, and who knows, maybe Android will sway you over - once you get past teething issues Android really is epic.
