Apparently you haven’t run all windows software.
No, I haven't, but I do run a cross platform consulting business. . . and I have yet to see a piece of software that will not run on Apple hardware. Given the physical construction of Apple hardware, there may not be enough slots available for some additional hardware on modern Macs but there are ways around that if one wants to go through those hoops. I don't recommend that. In that case, a PC is a far better choice. However, the discussion was about software and there is nothing about a Mac's architecture that precludes it from running any software that will run on any other computer that will run Windows based software. In fact, it will, as many reviews from Windows centric reviewers have asserted, Apple hardware will generally run it better and more reliably.
