My cousin is debating switching to ATT for an iPhone, or sticking with Verizon and getting a Droid. I suggested he decide by answering the following questions:

1) Would you use your iPhone as an iPod? (iPhone outshines Droid as a music device)
2) Are you someone who would explore and take advantage of mobile apps?
3) Will you be as productive using a virtual keyboard?

If you answered 'yes' twice or more, get an iPhone.
