Well, good. We're entering a golden age of OSes -- I run Windows 7 dual-boot with Ubuntu, and boot using USB to Android x86 or Puppy or TAILS. And sometimes I use an old Mac. This is not to brag, but just to point out that there's a lot of room to play. When SteamOS comes out maybe you'll find your Linux experience stands you in good stead.
Frankly, the experience of staring at a Windows box hung on a boot screen after an Update Tuesday motivated me to move to Ubuntu for most purposes. It's a huge relief to know that if my laptop OS glitches I can boot to another OS and go online to find an answer.
You might consider keeping a USB stick with Ubuntu or Puppy handy, and make sure your BIOS lets you boot from it when you really need to!
And yes, good luck!
