Well i’s a sleek machine and performs multitasking as it should. But think twice if you’re a power user:

Typing:
Sometimes the next pad is pressed because they are quite small. Why doesn’t the interface turn when you rotate the phone sideways, it does when you play a movie? I guess this would also help ease typing a bit.

Connectivity:
No dial up networking? f#k… this phone just connects as a ‘photo camera’ to my computer, and that’s probably the crappiest thing on the iPhone.
