I find the S700's ergonomics a bit frustrating. First, all the buttons feel the same, as does each pole on the navigation switch. Even if you get used to them and can find them by feel, you have to fully depress and hold the buttons; if you try to move quickly, you end up making a lot of accidental changes, such as entering macro mode or turning on the self-timer instead of changing the shutter speed. Also, oddly, you increase shutter speed/aperture by pressing Down and decrease them with Up, which can be can be difficult to adapt to.
