OS X Mountain Lion this Summer!
When I first heard this on Twitter, I thought it was a lie, but that's only because it didn't come through the normal channels. OS X (no 'Mac' on the front) Mountain Lion (10.8) is going to be released this Summer, and will then be on a yearly release schedule like iOS. Some of the new things I'm excited about are a more general inclusion of iCloud, the unification of Messages across iOS and OS X, and, of course, Gatekeeper. This is going to make it a lot harder for folks to slip in viruses and malware for my family. It's something I've tried to drill into them, but I'm afraid they still don't see it.
With Gatekeeper, the OS will do it for them. I like that.
I'm sure there will be a slew of other nice little updates, but the yearly updates are exciting too. The Mac is the best platform on the planet. I really believe that. Wonderful news!
