Spyware is another negative. I recently spent 4 hours getting the spyware off a Windoze (Win 2000) computer in my wife's office. The spyware had filled the desktop with shortcuts to porn, gambling, and teen sex sites. This vicious software even blocked the download of the programs designed to delete it. I had to download from another machine, put it on a disk and load it on the infected machine. I don't think there's much spyware for Macs. > >I would think that the virus problem to which Windows machines are >both susceptible and targeted would be a major factor in a final >decision.
