Neither UNIX or Linux has any GUI that resembles XP or anything past Windows 2000. The Windows GUI is built into and attached to the Windows kernel. That's why you can't ditch the GUI and work straightaway on the Cmd line in DOS. Linux at best resembles Windows 3.1. I remember the days of Windows 3.1 desktops and Windows 3.1 server running on Netware 3.1. You could unattache the GUI at anytime and go right into a Cmd line and get down to the dirty work that had to be done on the hard drives or driver setups. To compare GNOME or KDE GUI's to XP -- Wow -- that's an insult. I've tried to get the Linux developers to build a GUI into the kernel -- but, I guess Linus isn't haven't anything to do with that. And Windows 8 is but, the forefront of what's to come with the Windows 8 OS which is will become completely voice activated everything within a few years. A whole new market. Eventually I can see even the Gorilla glass touch screens being gone. Seriously -- though -- comparing GNOME/KDE to XP??? Wow!
