Thats interesting, i'll have to look into Concert a bit.
Its good that MS supports old OSs. When i went from Tiger to Leo i lost almost all my 3rd party programs, but switching from XP to Vista only lost one or two which. It would be great if Apple gave a crap about legacy app support.
I should have said that "concert" is the pronounciation of "ConcRT", or "Concurrency RunTime".
You probably won't get many hits on "microsoft concert", but "concrt" or "concurrency runtime" should do well.
Microsoft is putting the multi-core threading support into the Visual Studio runtime libraries, not the operating system. Therefore any product can ship the redistributable DLLs with their code, and add ConcRT to old systems.
Brilliant.
No, it really is bigotry(although I don't mean to imply it on your part; sorry for that.). And most of the insults come from the Intel fans, who really have no stake in the matter. SL may include 32-bit support, but if you expect to run it in 64-bit mode, you will need 64-bit drivers. Apple will include their own drivers for many products, but 3rd party hardware will need to provide their own. Many older Apple products will probably see no 64-bit support, just as PPC sees no support. (Potential examples on Apple's part, actual status unknown by me: USB Modem, Firewire iSight, older printers, scanners, etc.)
Yes, and it says 64-bit Applications will have no problem with your hardware, which presumes you have drivers. It doesn't say the hardware will work in the first place, because Apple can't promise that.
Shhh.... Apple wants to claim that Windows has x64 driver hell, without admitting that Apple is joining the same club.
..., because PPC is already supported by OSX, just as 32-bit Intel is already supported on OSX. The hard work for both has already been done, and dropping PPC is not an example of 'saving' hard work, just as keeping 32-bit Intel doesn't really create new work.
Testing, QA and support cost a lot of money. Apple is indeed saving work and money by dropping support. It won't save much engineering cost, but it will save money.
