I own an iPad and really like it a lot. I am considering buying a Macbook Pro 13", but an not sure that I need it, since I own the iPad. My primary use is web surfing, and email. I like the portability that the MB Pro offers, but of course the iPad has even better portability. I'm curious - those that own both an iPad and a MB Pro, what do you find the advantage of the MB Pro is over the iPad for web surfing and email use?
