Adam Richardson has written an interesting article for Cnet about why he switched from the BlackBerry to the iPhone, and then switched back. Although Richardson liked both devices he says, “basically it comes down to the fact that the iPhone is really good at the stuff I do 10% of the time, but pretty poor at the stuff I do 90% of the time.”

The iPhone is a fantastic device to handle photos, Internet, and media but the BlackBerry does better at the core functions that involve typing, like email. The article lists a long list of iPhone upsides and downsides and it's definitely worth the read.
