Everyone has choices.
You can build a (PC)Hot Rod you can tinker with that'll run circles around anything. It can also explode into a ball of smoking blue screen if you're not careful.
Or, you can buy a (MAC) that has 1 speed.
Will run till the next ice age? yes!
Want to upgrade it - sorry
Want to make it faster - sorry
Want to add something - maybe
Also, IMPE, PC's were made for business applications
MAC's were built and have been cutlivated for graphics, music, art
Why are there still a PC's? I believe because Apple wouldn't license the technology.
