As the title says, Im currently on android right now (galaxy s 2) and I've been toying with the idea of trying apple out. I like android but it drives me crazy that it's so fragmented and phones come out so fast that it's hard to keep up! My concerns are if I purchase an 4S is how long till the "phone 5 ..... err 6" comes out? I dont want to purchase it only to find out a new model is coming soon. also now that I'm used to using a 4.5 inch display will I be able to go to a 3.5 display? Are there any users out there who have switched from android?
