Quoting Thrax

Vista is Windows XP Service Pack 3 with a bunch of useless crap and the DRM PLUS! pack.

Usually you present your opinion-based arguments with well-rationed logic behind them - but this is below your standards. Vista is quite a bit more than a service pack to XP. It's almost a complete re-write. Dig into it a bit more than a superficial layer, explore the aspects that affect, say, the MCSE skills; the more technical side of things, and you must agree that your assertion is quite an understatement.
