I just purchased (mistakenly) a Windows XP professional for 64-bit architecture OEM CD that came with a coupon for a free Vista Upgrade. It was not returnable, unfortunately. I don't have a 64-bit processor in my computer. $139 takes it. I thought it was a great deal with the Vista coupon (though I loath Msoft and am a Linux user, primarily) -- Jeff Gelbard ph: 413-268-7258 fx: 413-268-0258
