This is probably the same reason they won't fully adopt Thunderbolt. While there are some reasons like licensing and requirements, one major reason is that laptop docking stations make a lot of money and customers often need to buy new ones with newer models. Switching to a cable that is universal will make them less money.
If it was so obvious, why haven't anyone thought about it before Apple?
Two things come to mind: 1) The bottom line. Many companies don't always do the little things because it takes time and money to do things. I'm pretty sure an engineer from another company came up with great ideas but they were cut in planning/development. Apple will spend years on a product before releasing it and they will charge enough to make this strategy work. 2) Featuritis. Many companies focus on too many features. This is related to #1. Following the history of Apple, their products never have the most features. Apple seems to focus only on a handful of them and get them right before adding new ones. Geeks here don't appreciate that as Apple will never win the bullet point count, but for the average consumer they are less impressed with numbers of features than working features.
Take for example, the original iPod that synced automatically when you plugged in the cable. I think it was at Jobs' insistence that this be a 1-step process. Now doing so isn't technically difficult, but it takes coordination between hardware and software. It also required a philosophical change away from file/directory based transfer to one based on metadata. For example, most people don't care which directory/subdirectory their favorite songs where located but what they were (songs by The Rolling Stones, blue-grass songs, etc.). Now other companies might have been focused on other features like playing every format from Ogg to WMA or an equalizer with 11 bars, etc. Apple concentrated on making the UI simpler for the average consumer.
I see the problem as laws haven't kept up with technology. When the original law was written (1978), there were no such things as ISPs.
Mouse balls are now available as FRU. Therefore, if a mouse fails to operate or should it perform erratically, it may need a ball replacement. Because of the delicate nature of this procedure, replacement of mouse balls should only be attempted by properly trained personnel.
Before proceeding, determine the type of mouse balls by examining the underside of the mouse. Domestic balls will be larger and harder than foreign balls. Ball removal procedures differ depending upon manufacturer of the mouse. Foreign balls can be replaced using the pop-off method. Domestic balls are replaced using the twist-off method. Mouse balls are not usually static sensitive. However, excessive handling can result in sudden discharge. Upon completion of ball replacement, the mouse may be used immediately.
It is recommended that each replacer have a pair of spare balls for maintaining optimum customer satisfaction, and that any customer missing his balls should suspect local personnel of removing these necessary items.
To re-order, specify one of the following:
P/N 33F8462 - Domestic Mouse Balls
P/N 33F8461 - Foreign Mouse Balls
