I grew up playing LucasArts adventure games on a Mac. Those versions came with their own inbuilt graphic filter to smooth out the pixels. (It later went into much more widespread use under the name of Advanced Mame 2X filtering.)
Now that I've switched to PCs, I prefer the chunky pixels of the original versions.
But I suppose I can't blame people for liking smoother graphics... as long as the option to switch back and forth is readily available.
