Hey guys, first post on this forum: Anyway I am torn between getting a Macbook or a Macbook Air. I am aware of the differences (and the drawbacks the Air has however, I have an excellent iMac so it's ok me to to sacrifice the storage space and such for the portability). My question is more about the Macbook, should I get the Macbook now or wait? I seem to have heard about a full refresh of the line (something about Aluminum case?). Thanks.
