A little, but you have enough to get started. Rather an old bash than no bash. First task on OS X is usually to use the bundled curl and ruby to get homebrew. :)

Will be interesting when Windows comes (well via an update) with a later version of bash than OS X!

Hah, and that might not even take that long at the current rate! But we still got a better terminal emulator by default over here! Terminal.app is a pretty darn good terminal emulator, although iTerm2.app is better. That is actually one of the things I like about OS X - I have not found a terminal emulator for Linux (and certainly not for Windows) that compares with iTerm2. Not in speed, nor in interface.

I am pretty sure we will see a better terminal come out thanks to this new Linux sub-system or whatever they decide to call it.

WSL is only a CLI layer. The GUI is still cmd.exe.
