Thanks to Macgasm for pointing out that Apple is now giving away free DVD copies of Mac OS X 10.6 Snow Leopard to MobileMe users still running on 10.5 Leopard. This is to aid those users in making the jump to 10.7 Lion (which must still be purchased from the Mac App Store for $29.99) and thus iCloud before MobileMe’s 30 June 2012 shutoff date. Of course, a copy of Snow Leopard won’t help those still using PowerPC-based Macs, which can’t upgrade past Leopard, but if you’ve simply been dragging your feet, this is a nice enticement to make the switch.follow link
Use Expose to Open Files Quickly
Looking for an easy way to drag a file into a hidden application? First enter Expose's All Windows mode by hitting F9, then hover over an application's window while dragging your file, pause for a moment (or press the Space bar) and that window will spring to the foreground enabling you to open the file within that application.
