Dude...
Until FSB's are wider than eight-lane freeways, memory latency is naught and storage media has a lower read-time of light speed, the ball will be there... it's how computers work!
All it means, really, is that somewhere down the line is a bottleneck. For most, that's their hard drive. But even the snappiest SSD's can sometimes not appease the ball...
Beachball of death? Great, give the MS fanboys something to ***** about.
Since when does a beachball mean, "GET TO THE CHOPPA!!!" All it means is somewhere down the pipeline a process is waiting... for what? Who knows. Sometimes formulae simply get caught in an infinite loop <8O It's inherent of programs designed by fallible humans, so get used to it.
Besides, it happens to be a magneto-optical disk. In the same way Microsoft copped the idea and displays a disc icon beside the cursor when accessing optical media. Then again, what hasn't Microsoft blatantly taken? They haven't had an original thought since MS-DOS. OOPS NO! Hahaha.
