I seriously considering selling my ipad and getting a laptop as my 2nd computer (27" inch i7 imac is my main rig). Would be using it for school for note taking, put some music on it, web browsing and travel since I usually go away few a few weeks every summer. So I was deciding between the 13" mbp or the air but don't know what would be the better buy. I'm leaning towards the air more, but the new thunderbolt port it making the decision harder. Also how much more powerful is the dual core chip in the mbp compared to the intel c2d in the airs?
