I don't hate it, I don't like it. It's simply nothing special...
I feel this iteration is a step backwards for a number of reasons. The design as a whole is much less familiar as an iPhone and an Apple product. The classic silver bezel is gone as are the simplistic lines that grace all of Apple's industrial designs. By removing the curved backing, Apple has taken away ergonomic considerations, something they were careful to champion when the first iPhone and even the iPad were released.
A fair point - but as the iPhone gets slimmer, it's less important to have a curved back. As long as the edges aren't too sharp, it's not going to become a deal-breaker.
Same screen size = fail
A 3.5-inch diagonal display with 960 × 640 pixels works out to around 325-330 ppi. (Maybe even higher, if its more like a 3.4-inch diagonal.) Thats fewer dots per inch than on, say, a 600 dpi printer, but when combined with anti-aliasing, I believe the on-screen typography on the next-gen iPhones will be indistinguishable, or nearly so, from high-quality print. There will be four pixels packed into the space now occupied by a single pixel.
Good design is not how it looks, it's how it works.
Same screen size = fail
Now I'm laughing at the guy who said 60% hate the new design.
Seems coincidental that Macrumors creates this poll after what was said by that clown.
