I'm not sure what I should do. NC's tax free weekend is the 4th through the 6th, yet WWDC begins on the 7th. I'm in the market for a MacBook Pro but I would be upset if I were to buy it on the 4th if a new revision is announced on the 7th. I need a computer for college, which begins on the 18th, but there are computers available in the library. Should I buy on the 4th saving a few dollars or should I stick it out and wait for Merom?
