I'm not quite clear on the "disappointment" about the iPhone 5. The iPhone 4S has *every* feature (plus some) that was reported to be in the iPhone 5 -- it even has what many cell providers CALL 4G speeds, so what EXACTLY is the problem? Not expensive enough or something?
Aside to a.j.c: Siri *is* in the software, but requires a LOT of processing power, so it won't run on a single-core cpu like all the earlier iPhones have.
Personally I think this is the perfect update -- it's not so mind-blowingly amazing (well, apart from Siri) that everyone who's recently bought an iPhone 4 feels cheated, but it's also got more than enough new cool stuff in it that all those millions of people who bought a new iPhone and who's two-year contracts are nearing the end are ready to upgrade. Great timing, really.
The real "iPhone 5" is now clear to come out in 2012, which is ACTUALLY the fifth anniversary of the iPhone AND when genuine (not marketing hype) fourth-gen cell networks should be reasonably widespread (at least in the bigger cities). Seems like some nice symmetry to me, personally.
