@urluckday... yes, the vis-hysteria stems from people who were too lazy or dumb to find out if their old school kit was compatible with the new OS. Throw some DRM scaremongering in, and Vista's slow start in the mass market was an inevitability.
I have to admit, in the HTPC world, it was entirely teh opposite!! (usually is)
There was a mass of early vista users... vista media center being inbuilt into HP/Ulti, as well as being far superior to XP Media Center Edition, was polished and ready to from pre public beta, let alone RC1
I, and many others ran a fully functioning htpc on a pre public beta build for over 4 months without a major hitch.
