Well, I think you'll find that many people thought that it was damned amusing that Acorns could emulate PCs useing PCem. It kind of belittled the PC, which many people liked. And what's more, the emulator was cheap.
When it came to the PC card it was a similar situation. I got a PC card with my RISC PC for £99. I certainly wasn't going to get a real PC for that kind of money. For £99 it was a nice toy that allowed me to play the odd PC game and run the odd bit of software. An amusing extra that showcased the flexibility of the Acorn design. It was also Acorn's way of saying 'you don't need a PC because you have an Acorn'.
So, of course people are upset now the tables are turned.
And where are people getting this idea that Acorn was trying to push people into using Windows/DOS by providing PC cards and emulators? If that is the case then Apple, Silicon Graphics, etc are all doing the same. Odd way of looking at it.
