How is apple vs PC different from apple vs windows?

Oh man. Well, first of all, you’re about to be accosted by a hundred GNU/Linux users.

Secondly Windows is an OS, while PC is generally a hardware spec. Plus the PC on the right shows HP, which is not Windows, but rather a PC manufacturer.

What makes you believe more Democrats are apple users?

The whole thing is a generalization. I am generalizing based on personal observations.
