iPhone 3GS here. Also had the 3G. This has to be the best electronic
device ever invented. It will have to be pried from my cold, dead hands. I take on trips in lieu of my laptop. I love that I can access my PC and servers while in the woods camping etc. and the apps are endless. Web browser...way better than all competition and I've had them all from Blackberrys to Palms to Win Mobile
devices.
Oh, and I'm not an Apple fanboy at all. I make my living managing Windows environments but when Apple does something, they sure do it right. My father-in-law has the "droid does" and I played with it quite a bit but it just "doesn't" compare to the iPhone. The interface just isn't near as smooth and refined although I will say it's the iPhone's closest competitor IMHO.
