Happy for them. Back in 2004/2005, Ubuntu was what got me into the Linux wonderland. It was an amazing time. Canonical's work on the desktop towards the end was so exciting for me personally. Unity as a concept even though just partially realized is still my favorite ever DE. To this day I install little tools on my mac that give me some Unity elements like super+{1,2..N} combo. Part of me still wishes they or someone else can come back and finish that vision.
The original Unity design docs were so good but I can't find them anymore. Does anyone have access to them? They detailed things like workspaces, "windicators", HUD etc. It was an exciting time even though there were a lot of flamewars because of Gnome fans not being happy with Canonical doing their own thing.
