Ditto. Like a few others here I prefer xmonad though, but there are certain things that I use Windows for and it is fairly disappointing to not have the wm functionality.
As for the tyler wm video...I absolutely abhor quicktime. Never have a good experience with it.
As for tyler...a few questions:
are there keyboard shortcuts for resizing the main window, switching the active window to the main, switching active window to another workspace (in OSXs case another monitor)?
how does it handle popups (like download dialogs, or update dialogs)?
can you set it to float certain applications or application types like you can with xmonad?
Normally I use i3 on linux, but the few times I have to use Windows I really miss it.
