Chris, I agree. And as for Microsoft being a monopoly, not even close. As long as other options are out there, you are completely free to choose something else. Apple or *nix - take your pick.
Microsoft has better marketing, therefore market share. Apple marketed to end users in the early days, Microsoft marketed to developers and hardware manufacturers, which offered much better results.
As for myself, I'd rather hate Walmart (the evil empire). To each his own.
