I am considering purchasing the oem version of vista home premium with the windows 7upgrade coupon, Ivista and windows 7 dont format over a operation system anymore, they save the old files in a different partition, I dont want that, I want it just to be upgraded and keep everything the same. However, i love the way everything runs in 64bit(even my beloved freelancer), and want to go that route asap, so should i get vista with the upgrade coupon(109 bucks) or just want until october?
