Unless the news is os x mountain lion fixes most of lion's ****, nothing to get excited about.
OS X has lost all it's excitement anyway, no doubt since the b team of apple is developping it, when they do that is, it's become a very problematic os at its core, apple are right to be disallowing it from a older systems because it makes them resource hogs. Anyone out to extend the lifetime of their older mac should simply install windows, period.
They better be giving out for free btw, no one charges for a service pack, not even Microsoft, and with the things lion users had to endure it will be a common decency, of there's any of that left still at apple.
You are completely right, we shouldn't have to pay for major fixes and the return of old features, that should be given to us for free.
It really doesn't make any sense to buy back expose or why Microsoft will offer better support for "legacy" Apple hardware. Tiger came in two different versions for both Intel and PPC, could run with or without Core Image and ran BETTER than older OSes on the same older hardware.
Of course the old Apple that used to care about it's computers is long gone.
