Review iPhone 4

Glass and stainless steel, still the apex of modern design. Though it might sound like I'm talking about a Manhattan skyscraper, I'm really describing Apple's latest iPhone. The iPhone 4 departs from the rounded corners and (literally) feel good design of the past 3 iPhone models and goes for modern, angular sharp edges. It's a thing of beauty to look at, though I'm not sure I prefer it over the iPhone 3GS. Maybe that's a gender thing; women are supposed to prefer soft lines, but being a tech geek I'm not typical-- I actually loved the Motorola Droid's incredibly angular design. But that's up to you, prospective buyer.
