After seeing this question, it made me wonder: why don't Macs have hard drive activity lights?
It seems there is no actual meaningful use for them nowadays, so is that why Apple decided not to include them on Macs?
If so, why do PC manufacturers still insist on putting them on every single computer?
2Actually there are answers there which explain why it is needed. Since PCs don't have any CPU activity LEDS, sometimes it is difficult to determine if computer is just frozen or is it working at maximum speed. Too bad nobody after BeBox made blinkenlights for CPU status. – AndrejaKo – 2010-09-08T17:04:41.017
