I am thinking about buying a Macbook. I am pretty much in need of it now, but I don't want to buy one and find out that they are coming out with a new version in a month. Does anyone know if they are coming out with any upgrades in the near future, or am I safe buying one now? Or does anyone know what date the current Macbook was released, that might give me an indication of how long until a new version. Thanks.
