From [http://www.dummies.com/how-to/content/working-with-aliases-in-mac-os-x.html] as of 2010-05-15]:
- Aliases in Mac OS are like Shortcuts in Windows but better. Aliases usually don’t break when you move or rename the original file; shortcuts do.
- Alias feature has been on the Mac since at least OS 7 circa 1992. Shortcuts first appeared with Windows 95 in 1995.
