I don’t know about you, but I’m often driving or taking notes when I’m using my phone…
Try dialing a number with an iPhone in your left hand while steering with your right or typing in an address on that touch screen while jotting down notes.

The list was also extremely biased, but I’d expect nothing less from a site named crackberry.com.
