It's not just webOS. We should also be seeing a lot more Android tablets this year, which of course is Linux based as well. There's Chrome OS also, again, hard to say, but it likely will be on a lot of devices before the end of 2011. Ubuntu is used more than before, though it's not precisely mainstream for normal consumers yet. Still, with Ubuntu going with their own desktop manager with 11.04, it could possibly gain more traction if they really nail the user experience.

And, of course, iOS and OS X is based on BSD, and BlackBerry's Playbook will run a QNX based OS. Both of these are UNIX OSes. At the very least, more people than ever in recent times will be using *nix operating systems on a daily basis.
