The iPhone 3G barely had any improvement beyond the antenna and the 3GS was widely derided for being little more than "a faster 3G". The iPhone 4 was the exception to the rule of incremental hardware improvements. It really is kind of remarkable how subtle the changes have been with iOS and the iPhone. A front shot of an iPhone on its home screen would show nothing new to someone in 2007 using the first iPhone (aside from the resolution increase). But I'd argue that what seems like a liability to industry-watchers and tech enthusiasts is a profound strength for everyone else - consistency and familiarity trump novelty.
