We have a sales tax holiday coming up this weekend here in NC. This is about the only way I know of to save money legally when buying a new Mac here (we are supposed to pay use tax on Internet purchases from places that don't collect sales tax, such as Amazon). The problem is that the new Mac Pro is not available till Monday, so if I want to buy one, it has to be what is available in the Apple store today. Has anyone seen any reliable info on what exactly are the differences between the current lowest price, base config Mac Pro ($2499) and the one available to order on Monday? Trying to decide if it is worth the ~$180 tax to wait. I guess the other part of the equation is whether the current Mac Pro will be available for a cheaper price after Monday (either through Apple or other, as long as I can buy Apple Care), and whether that cheaper price is likely to be lower than the sales tax. I'm sure I could buy from somewhere that didn't withhold the tax and potentially get away with not claiming it on my taxes, but NC is currently going after Amazon to get this sort of info, and if successful in the courts, they will likely go after other vendors. So it probably isn't worth the risks.
