Thats sort of the paradox behind Linux's popularity.
The only way Linux will become more popular than Windows is if Linux allows user to do everything from the GUI. Ubuntu is pretty good at that - hence why it's newb-friendly, but the more you do that the more you defeat the purpose of having Linux.
I hope most people realize the true power of Linux and come over to it, but it's still got a long ways to be comparable in the user-friendliest/deadliest OS of Windows.
Both my computers are dual-boot and that's something I highly suggest to most people. There are things that run on Windows and wont, at least for the time being, on Linux. Games are big one in that field. Some work well on Wine, the majority don't.
