Well it wasn't meant as humour, you telling me you can play COD on Linux? and play it properly? as in, install and play without anything like Wine or Gimp installed?
It's great for servers, but for everyday use I found it too much like something trying to play at being a full on OS.
My favourite thing to do on Linux was update apt-get packages
Linux will never compete with Windows or OSX, it hasn't been comparable since the early 90's
You must be trolling....
Why would you expect to be able to run COD on Linux without wine? Would you try and install an N64 rom on windows without an emulator? And as for GIMP... you didn't learn much with your linux dual boot did you?!
Honestly, every point in your post sounds like a wind-up effort.
Still, back on topic:
I personally use Linux as my desktop OS because it's fast, free, secure, looks good, and to be honest i find it much easier to do almost any task in Linux than i do in Windows. I started using Linux about 5 years ago by dual booting, and found that i could do basic tasks in Linux, but anything that was more in depth i went back to Windows for. Nowadays anything more involved than playing Windows games and Linux is my preferred choice without a doubt!
It does take some getting used to, especially if you are relatively proficient in Windows as I was. Things seem to be in an odd place, or you need to look up how to's (which there are plenty of so that's all good

) and sometimes it just feels easier to get it done by rebooting to Windows.... so just go ahead and do that. As time passes you will find it happens less and less though and eventually you're quite happy in your Linux OS.
I always feel very exposed when using Windows actually, an almost agoraphobic feeling! Like trying to relax and get into a good book curled up on your sofa vs. trying to do the same in Heathrow with your passport, wallet, and tickets in a bag next to you - you daren't look away from them for too long
