The information regarding Snow Leopard (aka, OS X 10.6) is still pretty sparse, and has received little media attention compared to the 3G iPhone. That said, Apple’s Snow Leopard page is now live, and highlights some pretty neat tech. It should be pretty exciting to see what’s being done with Grand Central and OpenCL, though I suspect it’ll be a while before we see anything live. From reading about what’s planned, it sounds like 10.6 will primarily be focused around the “fit and finish” of the operating system, adding polish, speed, and reliability to the new technologies they’ve been piling into OS X with each new update. The last time we had a “polish” release was 10.1, so I’d say it’s due.
(For the server-geeks out there, the 10.6 Server page is here.)
