Not sure how reliable their numbers are and why InfoWorld don’t think the the Motorola Droid is the answer to every question, but to help you choose a phone, InfoWorld have created this calculator, where you can either select a profile that represents you or enter in the specific weightings for each category to get an individual set of ratings for the six mobile devices that may be tempting you today: the Apple iPhone, HTC Droid Eris, Motorola Droid, Palm Pre, RIM BlackBerry Bold, and RIM BlackBerry Storm 2.

Let us know what you think of it.
