What annoys me is that Nokia can't get their shit together with a real OS for their smarthpones, I wouldn't mind Symbian, but lately they have been changing OS faster than underwear and I hear rumours about them using Windows OS as a last attempt in the smartphone market.
Oh, well, I'll just stick to dumbphones, don't even need an SMS function, I literally only use it to call... or more often to recieve calls because people keep bugging me all the time.
As for design, last time I borrowed an iPhone from a friend, I got the sensation that it was the most uncomfortable phone to hold next to your ear and it's shape (a brick) did not make it more comfortable to hold the phone while talking to someone.
