Windows Vista is suffering similar problems which XP suffered from.
It was a rush job to get it out on the deadline given, which they still failed to meet.

All the XP fans here, remember Service Pack 2?
That was Microsofts way of repairing faulty goods.. another rush job.

Vista requires just the same, Vista Basic is no good, if anyone was to use any version, i'd recommend Premium. Although in saying that, i'd stick with XP until they release an update for Vista.
