How very dissapointing Shawn I always looked up to you and thought you were wise. I hope you were joking MS makes the greatest products out there no one can deny that but they have a tendancy to charge for those products. Windows, Office, Visual Studio, OneCare. All beat the competitors Linux, Star/Open Office, misc developing tool, Ad aware.
The only item on the market now that can beat Antispyware is SpySweeper. Since OneCare incorporates MS Anti-virus and Anti-Spyware it is safe to guess it is a good product though not the best.
