I think your keyboard is not working or you have the wrong setup. When I read mac it should say windows right?
I can just switch those words and your posting it remains true. Enjoy what you have that makes you happy. Windows is good for you great, It is satisfactory for almost 90+% of the pc users.
I agree with all you points but I don't understand something. You said about buying a mac and installing windows, yes you can do that. It is an intel pc, as is now you can boot in windows without having mac running at the same so that means you don't need the drivers.
This is the same if you want to buy a powerful pc in any store but you want to run linux, you have to pay for windows os even you are not going to use it. All the manufacturers have a contract with microsoft that any computer build must have a windows operating system. Unless you build your own or buy a preinstall linux pc then you have to pay for windows but if you install linux or unix, etc you can run that pc. if you have an specialized hardware then you will have some issues finding the driver for linux or whatever but that is the same for anything.
I just bought a Bosch Jigsag with the dust adapter thinking I can use my festool CT22, I was surprise that the hose does not fit the dust port. Same as drivers in a computer.
Something else in the market place there are some brands that identify the product like Kleenex and it should say facial tissue, or Gillette instead of razor blade, etc the same is "PC" for a windows machine. Dell and others make big computer for corporations that use intel chips but they run using linux, they still intel machines but definitely are not windows machines.
