No, not convincing me to get an iPhone at all, Apple got me a long time ago and with all the apps bought as well as iTunes Match there will be no question. Sold my 4 already as long as I got some money for it.
iPhone 5 looks sexy, no question, but my gaming has totally shifted to iPad 3, so what do I need a shiny new CPU and slightly larger screen for? Never understood why people want to carry around rather large smartphones.
Will the new CPU increase the usability of other apps like turn by turn navigation? Any other non-gaming apps that will profit from the higher power? Any new features that won't work on older iPhones at all?
Or is it really mostly that, the new sexy slim unibody design? Not that that wouldn't be a reason to get one. But when I think reasonable, I haven't missed anything on my iPhone 4, not even Siri.
Stop looking for validation from a bunch of strangers for something you know your going to buy but dont need.
