Too bad - I'm so glad that for the most part I'm off MS and on Linux.
As you may know, Ubuntu Linux is THE way to go these dayze - totally free, and with a fair share of killer apps. I've got 5 machines and all run Linux, with 2 machines dual booting into XP for those one-of-a-kind apps I need sometimes.
IMO, Most PC folks would be much better off running Linux, either standalone or dual boot along with MS XP.
Do all yer internet/email stuff via Linux and not hafta worry about intrusions and other nasties. Of course, spam can't be stopped no matter what the OS.
