As a long-standing e16 user I must say I'm not quite ready to switch. I love the `keyboardability' of e16, and e17 has let me down a lot in that regard.
None of the actions can be bound to my `window manager keys', Hyper and Super, and seeing as that literally everything(!) else is taken for something else in my setup already, it's very hard to get the `e16 feeling'. Shame, because it looks so good :(
