If you're a 50-50 guy, then I guess you're running LinBlows.
Don't make me do the math for the 3 boxes.

I could do it, but then I would feel more like an techno geek.
2 boxes of Linux = 66.67% Total
Dual boot box:
Linux 50% = 16.665% Total
Windows 50% = 16.665% Total
You're roughly
83.3% Linux uptime w/ those numbers.
