Worth getting the 13" Macbook Air for Xmas?

I've been mulling over which Macbook to get, having come to the conclusion that they're practically the best laptops money can buy and having a new found will to learn how OSX works (never owned a Mac before). I now have my sights set on the 13" MBA. The thing is I wouldn't be able to buy it until around Christmas, or even January.

So, my question is: With the upgrade cycle being what it is would I be cursing myself 5 months down the road? Should I wait it out or take the plunge?
