Windows The ARM version of Windows 8 might have just become the most desired version of Windows in our hearts and minds. After us talking about legacy code and backwards compatibility in Windows for years now, an Intel senior vice president, Renee James, has just stated that Windows 8 on ARM will not have any form of compatibility for legacy applications whatsoever. Update: Microsoft has responded to Intel's claims. "Intel's statements during yesterday's Intel Investor Meeting about Microsoft's plans for the next version of Windows were factually inaccurate and unfortunately misleading," the company said, "From the first demonstrations of Windows on SoC, we have been clear about our goals and have emphasized that we are at the technology demonstration stage. As such, we have no further details or information at this time."

If I understand it correctly it will be similar to the OSX switch.

OS9 Apps did not run on OSX. There were some carbon (fatt) apps that were compiled to run on both but these tended to not be able to take advantage of functionality a native (cocoa) application could in OSX. CoreAudio for example.

I can see MS introducing something similar (fatt apps) as I doubt they want to force their whole dev community to rewrite their apps from scratch.

Wrong I was there during the transition period, OSX in its initial form had a classic mode which allowed to run OS9 applications in osx, it was dropped in later revisions. The PowerPC - Intel transitions were similar, they added rosetta for that task which was dropped a while ago. Apple usually gives an emulation layer for such things which provides a certain grace period for a handful of years after that a clean cut is performed.

I was there too. Even there during the move to PPC. You shouldn't second guess the age of others ;)

Classic mode was an emulation layer. If you remember, used to load up the whole OS in a window first. OSX itself did Not run OS9 apps. Apple did a good job of making them Look like OSX apps though so it was as seemless as possible.
