I'm using it as my main drive. Reason - I can't boot back into mavericks on my mavericks partition (on my Mac Pro). I had downloaded while booted into that partition, and every time I try to boot from it, the Yosemite installer starts up. Booting with the shift key held down results in a grey screen.
However, it works well with my regular programs (apart from Mail which was a dog with Mavericks as well); and some programs run much much faster. So I'm happy to stick with it
