Yes, OK but - it seems to me that when a new software item is launched Apple has a history of singing the most exuberant praises to the latest capability they now have developed and only after demand has reached boiling-point do they, gradually, hint that you actually need to upgrade in order to take advantage of their new trinket. And - yes,... - well,, you know - you may have to, under certain circumstances, actually, in fact pay, you know...money... That strikes me as dishonest, and links up with a very basic corporate strategy. First you lure them onto the caroussel, then you charge them. ITunes, for instance, is not for listening to music but for buying stuff - from Apple! Air Play and Home sharing is very strategically developed and limited in order to enable people in the Windows camp to include Apple items in their setups, but never to make it feasible for Apple users to jump ship and go for Windows Media Center or Android phones.
Yes, Mirror was a key feature of Moubntain Lion. Less key was that it would not work with anything less.
The strange thing is that since I switched from Windows rto Apple a few months ago I find myself at every turn a little more disillusioned by Apple and a little less inclined to act from any form of loyalty or trust - rather than what I expected, more and more confidence in the new environment where everyting is taken care of and solutions are part and parcel of this excellent colour-coordinated universe.
And yes, I could buy Air Parrot, I guess, and it might work. But then again it might not. And at the next juncture I'd find myself having to make the choice again - paying to stay abreast of new developments and media or standing my ground and patching up my trusted set-up with another piece of gum...and another...and another...
The price of Mountain lion is higher, but not that much higher, and I have to trust(?) that after that upgrade everything will work. If not I'll just have to look around for another...isn@t there something called Leopard?
