I found a NEW MacBook Air 1.8GHZ with 64 SSD for only $1999 shipped to my door. Considering Apple may not introduce a new model next month, do you think it is a good idea to take this deal? I think a new Air will not be shown until its one year anniversary (MW 09'). Which will give this model 4 months of shelf life. At this price, it is about $1200 in savings. Your thoughts?
