Saw a friend's 5 today.

It does seem a bit zippier but the form factor is kinda weird.

If one spends a great deal of time watching movies on their phone then the increase in aspect ratio with no increase in actual resolution is probably a good thing but IMO the negative of letterboxed apps outweighs the improved "cinema" experience.

For those who use the phone more for apps than for watching movies there is effectively no increase in screen size.

I know, I know - just as with Maps they will eventually get it to work.

An iPhone 4S with the faster processor, 1GB of RAM, and the same connector, etc. would have been a compelling upgrade, the 5 - not so much.

In short, no - I am not getting an iPhone 5.
