If You're Ready for Vista, Vista is Ready for 512MB
Gizmodo says: If You’re Ready for Vista, Vista is Ready for 512MB.
While Vista probably won’t be out until after the holidays […] you’ll need at least 512MB of RAM (Read “2GB”) and a DirectX 9 graphics processor (Read “a Cray”) to just boot up.
I don’t see how it’s a problem. By the time Vista ships, every new PC will outperform these requirements by an order of magnitude and any two year old machine will meet them, so every working PC will be able to run Vista.
