Android File System Hierarchy

This is a very good idea. However, the interface isn't very convenient (especially having to mouse over items to get the description).

Does anyone know the reason for Android not following the LSB standard? Is this out of necessity or just to be different?

Cool, but why can't I see this hierarchy when I plug my HTC Droid into my Mac? I certainly don't see a /data/data directory, even with ls -a. Do I have to root the thing?

I think it would be nicer if the folders were grouped together (at the top).
