Hmm, I have to say I agree with the article. It's distinctly 'meh'
For someone coming from an older smartphone it will be a nice upgrade, but coming from an iphone 4 there's no real point. I already have a nice hi-res screen, I have no issues with 3G it's pretty quick, and 4G will be non-existent to patchy for the next few years at least. I use wifi when I need more reliable connection. The camera on the 4 is pretty good as well for what I use it for.
As a comparison, Nokia's downfall started when they changed their charging adaptor connector, previously you could guarantee anyone's house you went to, there would be a Nokia charger. Once that changed there was less reason to stick with them in the face of better alternatives.
I suppose if Apple had said - "we're changing the connector, but don't worry the battery will last 4 days" then it might have won me over.
In fact if the darn 'home' button wasn't starting to wear out I don't think I'd even need a new phone for another year or two.
Well I'm a Samsung fan-boy and I have to say, from a purely aesthetic point of view, the iPhone 5, like 4, lacks a certain sleekness, which for Apple is unusual.
