Go to the article and keep reading. He goes into Vista’s DRM failings.
We’ve bought a few new Dell computers recently; a fast single core for my father-in-law, a dual core for a client, and another dual core for ourselves. We wiped Vista off of all three. The box for the client and the box for my FIL are both happily running WinXP Pro. Ours is running Kubuntu. From what we briefly experienced with Vista on all three and from what I read here and elsewhere, I’m sooooo glad we pulled Vista off of them. Vista crippled all three boxes. (And that was without getting the DRM software into the mix!) It would have been a nightmare trying to support Vista.
I’ve put XP on the boxes I’ve put together lately. Avoiding Vista like it was radioactive. I am not alone.
