would LOVE to know where you guys get your grubby mitts on these releases! For me, as an average (non-dev) user, I like running the beta OS Xs for two reasons.
Firstly, I am studying Operating Systems at university, and its very interesting to see what these guys do to improve something I think works great already (save a few niggles). Case in point, OpenCL - which creative genius thought THAT far out of the box? (same goes for the guys at nVidia and AMD).
Secondly, its fun!
hopefully us average joes will soon see a leak from another source.
keep up the good work guys
