Admit it, native OSX apps were slow to show up - it took 2 years for Photoshop 7 OSX, otherwise you had to run it in Classic mode.
And you're missing just about everything I'm saying.
Allow me to list it out... simply:
Apple broke compatibility with the move from OS9 to OSX.
Apple broke compatibility in their move from PowerPC to Intel.
Apple changed their entire direction with the new OS, OSX in 2000.
OSX does not support legacy applications from OS9 and previous natively... Classic doesn't count.
Microsoft needs to do the same thing.
Microsoft needs to break legacy support.
Microsoft needs to stop trying to run software from 1993 on a machine in 2007.
Microsoft needs to cut legacy support, move forward with their OS... much like Apple did with OSX.
About you being a lifetime Mac user; means nothing in regards to this other than it furthers the idea that you might not know more about the Windows world, but that's not what is important. In fact, your footer, your prior usage, none of that is important.
What's important is that Apple broke legacy support with OSX. Microsoft didn't with Vista... the incompatibilities that people are seeing are a sign of what's bad/wrong in the Microsoft camp. How in the world will you develop an OS for over 5 years and not have compatibility out of the box? That's Microsoft's dilemma... or the start of it.
Problem is though... when you break legacy support, you should have upward support within the same OS branch... something that Apple neglects or uses to force OS updates.
Case in point... Apple Motion. It forced an update to an OS that supported CoreImage, CoreAudio, CoreVideo presentation layers... so that was a 10.3 and higher update that was needed for that.
They could have gone the Microsoft way, extend that framework (.NET) to previous versions in the same branch - so to OSX 10.0.0 to 10.4.8 - and go that route... but Apple breaks a lot of compatibility with each and every major revision (from 10.2 to 10.3)... so Apple isn't a saint either.
Breaking legacy support is a gamble... but Apple had to make that switch... OS9 was a dead end.
Vista just came out. It took some years for OSX to get Photoshop, Quark, Illustrator, Flash all native OSX. Same type of growing pains... just that Microsoft should have coordinated the move with the software vendors in regards to Vista to shorten that time.
