Roundup of OS X 10.8 Mountain Lion Features and Notes

Apple surprised everyone this morning with a developer preview of OS X 10.8 Mountain Lion. The new release brings a number of iOS-like features to the Mac, as detailed in this video:


- Messages - new version of iChat with iMessage support
- Reminders - create lists and tasks, synced via iCloud
- Notes - create notes, synced via iCloud
- Notification Center - on screen pop-up notifications
- Share Sheets - share buttons to email, tweet, message, etc...
- Game Center - social gaming center for Mac
- AirPlay Mirroring - broadcast your Mac's screen to your Apple TV

Apple also released a public beta of the Messages App for OS X Lion users and is available today.

They haven't mentioned a single feature related to pro users. Nothing. It's all about being a consumer, consuming video and sharing your unemployment stories with your friends.

P.S. Why am I a newbie even though i joined in 2003?

And we need game center on our Macs why?

To play games with friends? It's a perfectly understandable addition to OSX.

This annoying checkbox from Lion is finally fixed!
It remembers his 'state'. So you don't have to uncheck it anymore.
