Apple is packing 250 new features into the next version of Mac OS X 10.7 Lion, and most prominent among them are muli-touch gestures.
With iOS, we have been taught how to interact with a computer through touch. With Mac OS X Lion, Apple is bringing all of the same core concepts to our MacBooks, and desktop Macs via the Magic Mouse and Magic TrackPad.
Interestingly, Apple reporting that well over 60% of their Mac sales are MacBooks, so if you feel that all this muti-touch stuff favors the notebook family -- I'd have to agree with you. I'm not sure how how well these new features will play out, say with a Magic Mouse which looks to have about half of the surface area as the track pad on my 17-inch MacBook Pro.
Regardless, of how you interact with your Mac, I'm less worried that Apple is trying to "dumb down" Mac OS X to work more like the iPhone. I think today's announcement of new Mac OS X features are impressive and that I'd most of them.
In addition to Multi-Touch, Apple demoed nine other tent pole features, including: Full-Screen Apps, Misson Control, the new Mac App Store, Launchpad, Resume, Auto Save, Versions, AirDrop, and a redesigned Mail application. Mac OS X 10.7 Lion will go on sale in July for $29.99 and will be sold exclusively via the Mac App Store. Once you purchase Mac OS X 10.7 Lion, you will be able to install it on any Mac that you own and have setup your Apple ID account on. Additionally, for those people who need it, Mac OS X Server is now a separate applications bundle you buy from the Mac App Store. The server bundle is expected to cost about $50 and it is no longer a separate operating system that you have to purchase.
