That's a tough question for me to answer. The truth is there are a lot of phones on the market now that probably wouldn't have existed if the iPhone hadn't first paved the way. At least not for a while. RIM, LG, Samsung, HTC all had great devices available already, but the iPhone changed the standard for them all. We have things like Android devices today because of the massive niche that Apple carved with its innovative capacitive touch, efficient and stable computer based OS (WinMo is a joke), and much more. Sure the first generation lacked in some basic functions like picture messaging and the ability to install third party applications, but the platform was so amazing that a community arose to resolve these problems on their own. Jailbreaking revolutionized the use of an already revolutionary device, and eventually forced Apple to implement the App Store, MMS support, and myriad of other fixes. My wife is still using a first gen iPhone and is completely satisfied with it. Truth be told I would probably have ended up using one of Nokia's Symbian offerings or a BlackBerry, as those were the only smart phones at the time that really gave me the use I was looking for. Even so, having experienced the iPhone from first gen to now, there is now no other device that I can live with, and I've tried. The iPhone simply outstrips them all.
