I currently have a pc laptop and I'm looking to make the switch to a mac. I'm planning on getting a 13'' macbook, but I don't know if I should wait to buy one. Can I go ahead and buy a macbook or should I wait until after the WWDC? I know there are rumors of a new operating system and I don't want to get a laptop and then have to immediately upgrade to a new OS. I just don't want to be one of the suckers who pays full price for something and then a week later they come out with something even better. Any suggestions?
