Yeah, the keypad on apple stuff are usually excellent. I struggled moving over to the S2 but seem to have it mastered now...
The only downside to them is the silly predictive text. There's sites on the internet that show mistakes users have made due to the predictive text, versus what they actually typed..
On the whole, apple i think really reserve themselves in regard to their devices.
The new Iphone 5 isnt really worth buying in my opinion. They could do so much better, but they save it, just so people rush and buy it and they make more money.
