6 is ugly. 5 was really stylish... 4 paved the way. Overall I'd say 5 is the best looking iphone to date.
They've gotten worse with each new design.
4>5>6
Disagree. The 4 and 5 designs were derivative of other design aesthetics. They drew from early 35mm camera design in specific. The 6 design returns to the 2g design DNA, which is completely unique to the iPhone. It isn't derivative of any other device. It's unique and to my eye much more beautiful than the 4 and especially the stretched out and compromised 5, both of which broke the original design trend and were lamely struggling to make the iPhone something it wasn't: an hommage to a piece of technology that became obsolete 20 years ago.
