The new MBP that I just got got befuddled by my bluetooth mouse (Razer Mamba X), to the point that it was literally unusable for a few hours...

While OSX was demanding that I identify a bluetooth keyboard... I don't have a bluetooth keyboard at all.

OSX is buggy and getting less and less usable. I'm finding myself working on Ubuntu and Windows more, than OSX these days.
