Lindows was interesting. Windows was much more relevant then, not as much web stuff going on, no mobile apps. Unfortunately, Wine was not very feature complete, so it fell on its face quickly.
Lindows launched in 2001 IIRC. At the time, Wine didn't have regression testing, so someone hacked up a simple test-runner in C, called it "winetest.exe", ran the tests on Windows 95, 98, NT 4 and XP, and submitted it the Wine project.
The idea was to capture how actual Windows works, so Wine could implement how Windows actually works, not how you'd think it works just from looking at API docs.
