喬布斯的原話：“We’ve done tons of user testing on this, and it turns out it doesn’t work. Touch surfaces don’t want to be vertical.It gives great demo but after a short period of time, you start to fatigue and after an extended period of time, your arm wants to fall off. it doesn’t work, it’s ergonomically terrible.Touch surfaces want to be horizontal, hence pads.”
OSX系統不支援觸控屏。
這裡並不是說mac接上觸控顯示器不能用，而是指，如果你外接一個觸控顯示器，手按上去也的確能點的動，但OSX系統沒有任何針對觸控屏的最佳化操作，比如在觸控板上使用的那些手勢操作，在觸控顯示器上就做不出來，你只能把觸控屏當作只有一個鍵的滑鼠來使用，實際上電腦也的確僅僅只是把觸控屏當作一個單鍵滑鼠來用，這根本沒有意義，沒有最佳化的觸控操作還不如老老實實用滑鼠。

總的來說，就是說“觸控屏必須是水平的，不能是垂直的，傳統電腦上不能用觸控屏，否則手會被累酸。
所以，在可以預見的未來，蘋果電腦作業系統都不會對觸控做任何支援。
