> In fact, most ideas you see in MacOS these days can find their roots in early (and often experimental) Linux interfaces (from multiple desktops, to launchers, to Exposé).
I am pretty sure it was the other way around.

Also, Exposé was introduced in 2003 before Linux counterparts (and requires a good compositor to do it well). In fact, there was a rush to write KDE/GNOME plugins after Panther was introduced. Sadly, most were pretty janky/bad until Compiz was introduced.
Spotlight (launcher/search) was introduced with Tiger in 2005, also much before Linux desktops started introducing it. Only after that, desktop search (e.g. Beagle) and search-based launchers like GNOME Do started showing up.
