so you have to buy this OS or its a free update? :D
C'mon, ET, you've been trolling the Apple threads long enough to know that the new animal name means you pay for it. Well, those of us who actually like it and use it pay for it. You are under no compulsion to use it, like it, or pay for it.
As I, and several others, have explained to you sveral times before, in OS X .x increments are major upgrades, easily the equivalent of moving from Windows 95 to 98 to XP... and just like their Windows' counterparts are paid upgrades. Service pack upgrades are the OS X .x.y increments and are free.
This is an upgrade of OS X from OS X.4.6 or OS X.4.7 to OS X.5
You know, Windows users get a pretty raw deal here.
To get all the features of Windows Vista, you have to buy Vista Ultimate and I'm sure that will cost north of US$300. If you remember, Windows XP Professional is a $300 product, and they appear to be preparing Ultimate, the only way to get both "home" and "business" features, as an even more expensive product.
Full-featured MacOS X for $129 looks pretty good in that context.
