This is pretty OT, but I feel like it is worth pointing out:

Personally - this is a question of individual preference, though - I do not mind the OS boot time itself very much (to a degree). Whether the system takes ten seconds or two minutes from reset/power-on to the login screen does not make much of a difference, to me, psychologically. But once I log in, I need to open all of these programs, make sure the windows are in the right place, SSH connections to certain machines are open, etc. I admit I am kind of obsessive-compulsive about this, but this is a far greater (psychological) barrier to rebooting than the OS boot time itself.
I do not use Windows at home, and my work laptop runs Windows 7 (I intend to keep it that way, too), so I have not been able to play with the Linux subsystem on Windows. But if you consider it as an alternative to Cygwin (which I do use), it sound kind of nice. Now if only Windows had a native, builtin X server... ;-)
EDIT: With Cygwin or the Linux subsystem, driver issues are not an issue, of course, because hardware is still managed by the Windows kernel and Windows drivers.
