From a more intuitive Spotlight to more useful Smart Folders to multi-touch control, Lion makes using a Mac more like using an iPhone, right down to the fact that you can't make phone calls on it
Mac OS X Lion: Five top features

Mac OS X Lion is here, and with the trademark looks and animations, it's definitely an Apple product. It's also the next step for the Cupertino company in making its Mac OS feel more and more like it's smaller mobile counterpart iOS, right down to the multi-touch control. Is it a bad thing? We think not, here's five reasons why.
1 SPOTLIGHT
Allows you to drag and drop directly from search results into another app. Handy for dragging documents directly into emails
2 SMART FOLDERS
A new “All My Files” view displays everything on your Mac in a cool new interface, and allows you to merge folders
3 LOGIN
You can add personal details to your login screen, in case you lose your laptop. Hopefully some kind soul will contact you…
4 NOT JUST FOR LEFTIES
Many multi-touch gestures require a right hand to activate – Launchpad, for instance. Start saving up for an implanted third arm
5 SCREENSAVER
Yes, it’s now a jukebox.








We're working to fix the problem right now and will have it working as soon as possible
