Is it worth it, Garfield?

I had to... (I repeat) I had to buy a phone, although not necessarily an iPhone. Neither did I have the choice to wait for iPhone 5's arrival in Japan nor did I have the time to check when it was actually going to arrive, so with an ounce of iStupidity, I got myself this iPhone 4S on a contract... just ONE DAY before the iPhone 5 was unveiled!

However, having looked at the incremental feature improvements, I am wondering: is it really worth it? Garfield, what do you think?
