It can be a great tool too. I think anyone who discounts smartphones as just another "consumption device" are missing part of the usefulness of the network. I use my phone in place of paper logs for calorie counting and training. It's definitely been a solid replacement. It's probably shaved an hour a day off the odious task of counting calories, and having internet access means that I'm only a few touches away from form pointers and useful advice. I could replace it all but I'd have to start carrying about 40 pounds of books around instead.
