In the battle between Windows and Mac OS X, we've rounded up 10 features that Apple developed first, only to have them borrowed by Microsoft.
3. Aero Peek: Exposé
The Windows 7 Aero Peek feature that makes all windows vanish at once debuted as Exposé in 2003 with Mac OS X 10.3 Panther.
The two platforms' versions each has other things they can do, but Aero Peek and Exposé both let you quickly see the desktop of open windows and just as quickly bring the windows all back again.
Aero Peek makes windows completely transparent, removing all content. Exposé slides them out of the way.
4. File previews
File previews are all over Windows Vista and Windows 7, including the Preview pane in Windows Explorer windows and Taskbar previews, but Apple has always been ahead here.
The Preview pane came from the column view in Mac OS X 10.0 Cheetah in 2000.
The Windows Preview pane has now caught up to Mac OS X's with the ability to play audio and movies, but it still doesn't display text formatting.
Mac OS X 10.5 Leopard added the Cover Flow view for rapid viewing of multiple previews, but the ultimate preview is its Quick Look, which is resizable up to full screen - and lets you look at every page of a document.
