I have a PowerBook G4 and have been anxiously waiting MW 2008 before diving into a laptop. The MBA doesn't seem like it's going to fit my needs, but Im anxious to get a new laptop. I was really hoping the MBA would be for me and give me some piece of mind about buying something new sooner rather than later, but it just didnt pan out that way. What do you think? Is Apple getting ready to update the MB and MBP lines? Is there a imminent upgrade to things like the larger multi-touch track pad coming to these lines soon? Thanks for any help.
