My iPod Touch is almost identical to an iPhone...just not a phone. I can hop on wi-fi all over the place for free and check email, pay bills, surf the internet, etc. The screen is small, but access is fast, and I can zoom to see things just like on an iPhone.
Several of my colleagues have iPhones (they bought them from AT&T and then cracked them to work with their Polish SIMS). I just don't see any benefit for me though. Also, for a phone, I think the battery on my iPod Touch doesn't last long. I hear the iPhone has the same problem.
If I could talk at no cost through Skype on it, I would be convinced to throw away my trusty mobile phone. That day will come soon, I think. That is the day that AT&T, Sprint and Verizon will be killed for good. No more damn two-year contracts, no more crappy customer service...just free wireless calling anywhere in the World.
If I had the money to build that device, I would quit my job and start building it today. I would call it "The Sword" or "Dragon Slayer". The ads would be so cool, with the bearer of the Sword lobbing off the head of the "Can you hear me now?" guy and other stupid mascots and spokespersons. There'd be a special ad just for William Shatner, not because he is a wireless mascot, but just because he is annoying. :lol:
