I remember using OS X in the early years of its existence, and it was non-stop spinning beach ball of death. I switched to Windows for a while and then Ubuntu in 2006 which I still use. Everytime over the past 10 years that I try out a new Mac laptop or even desktop, the spinning beach ball still happens, even just clicking on a text field, despite faster processors, more RAM, SSD, etc. I see it in Windows 7 & 10, too, but basically never in Linux.
