Wonder when was the last time you even touched Windows. Vista maybe? Fix problems? I can't remember when the last time I had a problem in windows 7 and it's not just me. I know plenty of clients who don't have problems.
Of course you have the real support problem with Linux. Install the latest Ubuntu version [12.04] and Canonical will support it for how long before you have to upgrade? Every time you upgrade your system is down for a while during the upgrade and then you find out something doesn't work.
Or maybe you want a nice MFP but drivers aren't available for Linux except maybe some odd workaround that gives you partial features.
Don't tell me this never happened in Linux...
