In a few days I will be going to University of Washington (Seattle, WA) ,and the place where I live is just a few miles from the Apple store in UW. So buying a mac there would be so easy, but the tax would be included since the tax rate in WA is 9%. Well, in contrast, tax in Oregon is 0%, so I can save a lot of money if I purchase MB991. The only trouble would be that it might be a bit inconvenient to head from Seattle to Portland!!! So where do you guys recommend???
