I like. iPhone 4S arrived this morning.
I did skip 3GS and 4, though - got rid of my iPhone 3G six months ago and have been using an HTC Evo since then. I won't be sorry to see the HTC go; Droid is nice in some ways, particularly if you're into endless tweaking. But at my advanced age I prefer the simplicity of iOS. New features all look pretty good.
Having a bit of a marathon sync and upgrade this week - four iPads to update and two new iPhones to set up, plus MobileMe to iCloud migration. It's exhausting.
Tomorrow I'll see how the 4S plays with Ford Sync (which the Droid is pretty good at) and ask Siri some silly questions
