As someone who jumped from Windows XP to Linux (Knoppix, Ubuntu, and Arch) and now back to Windows 7: 1) No driver issues. I've heard bad things about Nvidia Optimus drivers for Linux. 2) I don't have to worry about not being able to install software, or other compatibility issues. 3) Games (the Mac gaming situation is pathetic). 4) It doesn't force me to muck around with the system all the time. 5) Windows 7 is actually really pleasant to use - much more so than XP or OS X; out of the box, it's only a bit less pleasant than Arch after I've spent a day installing and configuring software.

My misadventures with linux include forgetting to set up a netbook to connect to unencrypted wireless networks and the latest kernel update breaking wifi after suspending or hibernating; I've never had to deal with any of that on Windows. The most time that I've spent on system administration has been switching to an SSD, which became extremely easy after I found the right software to mirror my disk.
