Honestly, I could care less if it gets delayed for a lot longer. Windows XP is already a good OS. So why even worry about Vista for a while. I am not looking forward to that new OS. Tons of hardware and software probably won't work with it and we will all have to learn a new Microsoft OS which as always is a pain for most technicians a like.
Let Windows XP stick around a lot longer. We don't need a new MS OS anytime soon. Let Vista keep getting delayed for all I care.
