The iPhone is a HYPE machine.
If you love it, you don't really know how to use the advanced features on the other cheaper devices.
1. For AT&T, The Tilt, is 5 times the device and over $100 cheaper.
2. The Voyager from Verizon. Again, 5 times the device.
3. Any of the new Blackberries on ANY carrier. Wifi built in, unending data options, and the coup de gras.... CORPORATE e-mail.
4. The New Samsung Glyde at Verizon is a great (and smaller) Mp3 touch screen device with a qwerty keyboard.
So, depending on your needs.... There are many more reliable, cheaper, more user-scentric devices that you should get. No removable battery??? No keyboard in landscape mode??? WTH???
You know a phone is a piece of crap when you walk in an AT&T store, talk to their employees, and find out that NONE of them have one. Managers, Sales Executives, B2B reps, indirect reps/employees, Agents, etc..... NO ONE HAS ONE. My guess is less than 10% of all AT&T employees have an iPhone.
Seriously.... Video, MP3, WIFI, Hi speed network (like UMTS or EVDO), and best of all..... CHEAPER!
As far as Apple Computers..... Totally different....They rock. Get one. The iPhone. An overhyped, overpriced, underperforming piece or very pretty plastic & metal.
