My kid wants a laptop for gaming... he's been using my MacBook Air for KSP and Minecraft for a long time, and I won't be buying a new machine until the new models are out and proven... so I've conceded to getting him a gaming laptop for the time being.
It'll be Windows. It'll probably be our only Windows machine for the foreseeable future, but I know we'll have to de-clutter it when it gets here. And I still need to research that.
