That's a cool one, very fun to play  :Thmbsup:

Well I didn't want to turn this into an anti-apple rant thread ;) but while you brought up backwards compatibility this quote from the article I linked seems extraordinary to me-

The day of arrival was never a disappointment. The drama of it all – breaking open the wholly unnecessary white box, wasting half a day on the installation, playing with animated onscreen bits that pop up or slide about, copying files from drive to drive simply to watch the new progress bars – was worth the trouble of half my old software not working properly any more.

This is why Apple will never move into the corporate world, businesses need an OS which can run applications from 10 years ago, if not 15 years. But I digress, of course with Macs "everything just works".
