Hello All -
I'm about a week into using my SR, and its getting a bit easier. I've been on the iphone since the original one. As someone mentioned earlier, if the iphone 5 does come out with a screen greater then 4.2; and works on the LTE network, there's a good chance i'd go back.
There are some really nice things with the android OS, and some really tough things that I have to get used to. One of the biggest issues is the keyboard, I am probably 10x slower on they samsung / android keyboard inputs. It was extremely frustrating. Someone mentioned Swiftkey here and that has been very helpful.
You have totally missed the single feature that is the iphone killer for me. "long press" on any input box, select input method, and select SWYPE. Unlike swiftkey, it is built in. It is so much better than the single key input that iphone has.. or the reg keyboard on the android. I can write long notes with just my thumb. No fuss no muss. Try it and you will be happy.
