The iPhone was "essentially useless"? Hardly. Right up to the week the iPhone came out in 2007, cell-phone makers were telling us "there's no innovation left in this industry." Then Steve Jobs came out and turned the industry on it's ear, just like he did with the computer industry and the music industry.

Granted, I never owned an iPhone until the 4S came out (which I now have and love), I certainly wouldn't go so far as to say that it was "useless". At the very least, it raised the bar for software design and development. If you need proof of that, go look at the Android OS before iOS came out, and look at it now. Clearly, anyone involved in making mobile phones has been influenced by Steve Jobs.

I just got my first iPhone earlier this month, and I spend far too much time on it. It's helped me in just about every way imaginable, from staying connected with friends and family to saving and sharing special moments with them. On top of that, it's a wonderfully productive business accessory, helping me keep everything in order and on time. Love my iPhone, wouldn't want to be without it.
