My Win7 computer boots faster.
I gave up on Linux. It reminded me too much of the days of Win95 and Win98--it's a GUI that runs atop DOS. The only Unix I would have is HP UX, but that's pricey.
Solaris kinda-fanboi reporting in. I dabbled in Linux in my earlier days. Did some VAX/VMS. Got thrown to Solaris around 2.4 and have not looked back since. I rather enjoy it, though its future is a little hazy under Oracle. Back when Solaris 8 was still the big thing, and Solaris 9 dropped x86 support (no, wait, we were only joking,) Sun released Gnome and KDE packages. I installed both and far preferred Gnome over KDE. Anything over the CDE built in, even with its nostalgia value.
I had been exclusively command line in Solaris 10, though I did a recent VirtualBox installation of 10 with the Gnome desktop. Still seems pretty sharp to me.
