Vista, driving me straight to Dell

I have a client with a Dell XPS, Vista Home Premium, Gorgeous machine, totally useless,
makes 98-SE on a 486-DX2 look like a fireball.

I have heard Dell was supporting XP-Pro “downgrades” although seems more like an
upgrade to something that works.

At this point the Dell E-mail system does not recognize the “service tag ID” or “Code ID,”
there is no general delivery without the product codes the phone robot also will not let
you speak to anything with a pulse rate, I’m pretty much finished with speaking to things
with a clock rate unless Ray Kurzweil built it,

Any suggestions? (besides were microscrewed)
