Whats a real load of crap, is buying Windows Vista; especially when you can get this OS X update for fraction of the cost.
In all seriousness...
Vista will eventually overtake Windows XP in terms of installed userbase. But it will never happen as a result of upgraders, rather it will just be due to attrition once you can no longer buy PCs with XP pre-loaded.
I suspect that retail sales of Windows Vista as a standalone product will never add up to a hill of beans. Why? Because, with appropriate accessories (which should have been included with the OS for free, can you say Anti-Virus? ...oh well...) XP works just fine for most users. There's just no overriding incentive to upgrade. And when the time comes to finally replace your PC, the replacement will likely come with an OEM copy of Vista preloaded.
Microsoft and most 3rd party vendors will likely continue releasing new application software that works with XP for years to come still. (MS only stopped providing official support for Windows 2000 with its current-version Office software this year. Most 3rd party software you can buy off the shelf still supports Windows 98.)
An interesting question that comes to my mind is this: This forum is frequented by a disproportionate number of technical-minded people who actually understand what an OS is. As such, there's little surprise that the majority of users are at least interested in the possibility of upgrading to Leopard. But in the population at large, what percentage of Macintosh users are actually going to make the upgrade? And out of all the people who don't, how many are actually going to experience a tangible harm as a result of not upgrading?

if me and five friends buy the family pack will we be able to install it on all five of our computers. Also will it work if some are intel and some ppc.
Is there any technical measure that Apple could take to prevent you from installing it on all five computers? Probably not.
Is it permissible or legal? If all of your friends who get in on this are roommates, then I'd guess the answer would be yes. (Assuming that you actually meant you and 4 friends, not you and 5 friends. Remember, 5 + 1 = 6.

) Otherwise, no.
