iphone 5 won't be different from previous.

PCMag just reviewed the non-Retina version of the 15-inch Apple MacBook Pro, and when it came to evaluating its design, we were stumped. It is a little thinner and a little lighter, but it is basically the same laptop design that Apple has been using for years.

Did we knock Apple for not innovating? Not at all, although we did note the laptop's remarkable, shall we say, design consistency? The truth is theMacBook Pro

 has evolved into a kind of functional ideal where big design changes would either hurt usability or serve only as ornamentation. If it ain't broke, don't fix it. That is why I think the iPhone 5 is going to disappoint anyone who is hoping for a radical reinvention of the smartphone.

I'm not alone in this assertion. Much as I am loath to rely on leaked images of the iPhone 5, I can't pretend that I haven't clicked through every sordid, photoshopped gallery on the Web. (And yes, we published a few on PCMag.com.) There is a lot of crap out there, but some of the photos are so good that they aren't a stretch to believe. My favorite breakdown of the new iPhone 5's design is Don Lehman's on TheTechBlock

. All the leaked details are there: unibody construction, new dock connector, and an ever-so-slightly elongated screen to support a new 16-by-9 aspect ratio.
