These days, most of the games I play are readily available and work well on Linux. All of the Valve Source games have been ported, Civ V works great, many independent and upcoming titles on Steam have good Linux versions. Steam has been really good for Linux games.
I pretty much have no reason to reboot into Windows. I used to reboot for Netflix, but now it works in recent Chrome versions on Linux.
That said, I've used Linux as my primary desktop OS since 1995 (but always with a backup Windows partition), so I'm not the ideal person to look to for whether Linux is ready for the desktop...it's been ready for my desktop for a couple decades. But, I think now I'm at a point where I don't feel any need to have a Windows partition, for anything.
