Linux has always given me a headache. Windows has better software, better drivers if you know what you're doing it wont slow down.
I'm not saying linux is bad it's just too damn complicated for the average user. I'm well above your average user and I still find it complicated.
Also each new release of linux breaks something. The latest releases of linuxes I wasn't able to get mining working. Although a year ago it was simply plug and play. Or should I say plug and mine. I think that may have actually been cgminers fault, I may have installed the latest one that doesn't have Scrypt support.
Okay lets assume your kid want's to install a game on linux. They have to get you to install it and setup wine.
Kid wants to install a game on windows, download game, click the exe, install, play.
The only problem by me about Linux is. If something happens and all people die less 2 linux users, they use different distro. This is the problem of Linux.
The companies can offer good support on linux just for linux, its just a kernel.
Its nice have your
own system. You choose your favorite philosophy, but the price of that philosophy usually its problems.
