So this is the case; I already own an iPhone and the MacBook Pro, both purchased during last year. As much as I would love to buy the new iPad 3, I find a bit hard to motivate my purchase, both for me and for the people around me. So I am asking you guys; what are some things we the iPhone and the MacBook are limited in comparison to the new iPad? Work is that hard truth that an iPad would be completely on the necessary for me? Help me!
