MS proprietary file formats are supported by Open Office type programs.
As for 'specialty software' for hardware development and the like that's invariably ix code running under Cygwin or similar. This is why MS is pushing Linux embedded in Windows, its the usual "embrace, extend, extinguish' strategy that we've had decades of experience with. The big difference between running these platforms on an emulator and running them native is speed -- moving to Linux gives you a huge boost in speed.
