Apple.com has put up a teaser page for their next-generation OS X, 10.6, code-named Snow Leopard. And the features, to put it mildly, are mind blowing:
Exchange support built in, so that iPhone and OS X share common business email, calendar, and contact sync.
64-bit monster, supporting a theoretical 16TB (terabytes!!) of RAM.
Multi-core optimized, using "Grand Central" to chip away at one of the biggest problems in programming: how to really take advantage of multi-core processors.
Open CL, to co-opt the GPU into doing some heavy crunching on the compute side.
How does this relate to the iPhone? Aside from using what they learned making iPhone OS X, from optimization to shrinking the OS footprint, rumor has it Snow Leopard will go a long way towards unifying the OS X branches, leveraging development efforts, and in the end, giving the best of both worlds to desktop, laptop, and handheld users.
Great, I just got through WWDC 2008 and now I'm already jonesing for 2009. Way to go Apple!
