Every Mac lovers number one fear is buying a new Mac and 2 weeks later the one you buy is no longer the newest version. The problem with this primarily for Mac heads is that most likely the newest version is a bit faster, maybe cooler features and undoubtedly the same price.

Well no longer be worried about buying a new Mac, with a new site called Mactactic they have gages that tell you when it would be worth just waiting a bit longer for the next version. They even have estimates about how long you may have to wait for the next rev of the Mac.

Even better they have a Dashboard widget that lets you quickly glance every few days and see when is the best time to buy your mac. So if you’ve been eying a new 15″ MacBook Pro, it may still be a good value.
