I done both. Started with Android htc hero > iphone4 > galaxy note2.
I would say if you are happy with iphone screen size and not too tech savvy, you cannot go wrong with iphone.
There are more choices in android world, the only reason I switch from iphone to note2 is due to the larger screen.
I can do the same thing on my iphone and android. I think it's really come down to what you prefer, screen/bateery/size/looking/etc.
