Haven't "docks" been in use since BEFORE Microsoft introduced theirs with Windows 98?
Cases in point, NeXT OS, and IBM's OS/2 4 Warp, both used docks (a dock launch bar in NeXT's case, and a task bar launch bar in the case of OS/2. The Mac OS only picked this up as an official feature with OSX, while before that, you had to run a 3rd party app to simulate NeXT OS' docks (at least back in 1992 with System 7 on).
If one was to claim copying was made, then didn't Apple swipe their docks from NeXT OS (yeah, that was also Jobs' baby), and for that matter, didn't Microsoft in fact swipe their quick launch bar from OS/2 4 Warp?
And before any Mac fans mod this down in an effort to try and rewrite history, remember that the original Mac interface itself was swiped from Xerox PARC. They admitted to it themselves, and after introducing it to the mainstream, the idea of moving an arrow back and forth between graphical icons pretty much became the defacto standard.
It's that, or spend the rest of your life using CLI for *everything*.
