Pros: 32/64 bit flavors for half the price of the full disk. Very very easy to install fresh (without previous xp install), like most things on the net, it's a simple google search away.

Cons: still more expensive than linux ;P

Overall Review: DO NOT listen to the other reviewers, the workaround for a full install takes a matter of 2 extra minutes. Google is your friend. This is the real deal for half the price, Microsoft is well aware of this workaround, yet continued to leave it in after the SP1 update, nothing like a more affordable version of vista ultimate :)

Comments: honestly the best mem i've ever used, i've managed to get the timings down to 2-2-2-5 and run them stable, no errors what-so-ever when running memtests, nor does windows ever encounter errors, oc'd my 2800+ to 3200+ with ease, and this mem is encredible, ppl fail to realize that memory is the most important part of any system, so you might as well get the good stuff ;P
