Matt Alexander, of the two-first-names club, explains beautifully why the months of leaks and specification sheets don’t tell the full story of the iPhone 5 experience:
The bullet points we had so sorely sought to decry from Apple’s announcements have been translated into a tangible experience that exceeds the bounds of the reductive “iterative” moniker. Looking only at the specifications, measurements, and renderings of the iPhone 5, it’s easy to force oneself into disappointment. But, upon hefting the device from hand to hand, seeing the improved color spectrum, and watching as once-slow apps now devour digital content, it’s virtually impossible to see the iPhone 5 as anything less than an amazing successor to the iPhone line.
There’s so much that I could quote from this. The entire article is excellent.
