由前Xerox Small Talk工程師Bruce Horn寫的文章，裡面有提到其實像是Finder，桌面，Drag-n-Drop，這些都是由Mac Group所開發的，裡面這一段

As you may be gathering, the difference between the Xerox system architectures and Macintosh architecture is huge; much bigger than the difference between the Mac and Windows. It's not surprising, since Microsoft saw quite a bit of the Macintosh design (API's,sample code, etc.) during the Mac's development from 1981 to 1984; the intention was to help them write applications for the Mac, and it also gave their system designers a template from which to design Windows. In contrast, the Mac and Lisa designers had to invent their own architectures. Of course, there were some ex- Xerox people in the Lisa and Mac groups, but the design point for these machines was so different that we didn't leverage our knowledge of the Xerox systems as much as some people think.

更明顯指出Xerox的系統跟Mac的系統差別非常大，而我們今日習慣的模擬桌面系統其實還是Apple的作品，連xerox的工程都說了the design point for these machines was so different that we didn't leverage our knowledge of the Xerox systems as much as some people think. 其實Apple的UI並沒有跟xerox偷那麼多，只有精神方面是類似的，實用上卻是兩回事，雖然GUI還是無可諱言的是Xerox的發明，不過真的讓人們能快速學習，並認同的模擬桌面GUI卻是Apple的創作沒錯。

而Windows那種直接抄過去，左右相反，上下顛倒，黑白對調的作法，我認為就完全是抄襲了。

P.S. Small Talk就是xerox系統的工作環境，而雖然Bruce Horn是Small Talk工程師之一，不過後來他也到Apple工作了，所以不確定他的話要不要打點折就是了。
