The other thing is that GUIs can be very slow to load, limiting the potential speed/efficiency. One of the most frustrating experiences is pressing a series of key commands (or just single keys) that SHOULD have performed a very specific series of actions, but the software lagged behind at some point(s) in the flow and something ended up getting messed up because my series of key presses resulted in a totally unintended action.
