Leopard

Less than nine months after launching Leopard, Apple have just released a third update for their latest OS. OS X 10.5.3 claims significant improvements to Spotlight searching, wireless connectivity, the Automator, Spaces, and Time Machine, plus a number of other core and standard applications.

By comparison, Windows XP was released in October 2001 and it's only now getting a third major update in the form of SP3. Windows Vista was released in November 2006 and has only recently had SP1 released for it.

It begs the question of was Leopard fully finished when it was released 8 months ago or are Apple really that keen to continually update their products. I would hope the latter.
