Bugs crawling around Yosemite

Any of my Apple loving friends out there notice that the recent version of OS X Yosemite is buggy as all get out? It frequently locks up requiring a reboot and sometimes gives a “screen of death.” Running on a 2013 Mac Book Pro Retina, so no way to blame “strange” or “bad” hardware. Makes me think I should regress back to Lion. Honestly haven’t had this type of OS crashing issues since ye’ ol’ Vista days. Makes me wonder if Apple is spending too much time thinking about iDevices and is letting their quality control for desktop/laptops go to crap. If so, Windows 8/10 will eventually eat their lunch unless they come out with a nice touch interface for OS X soon.
