The eye tracking looks great, just as a regular additional way of using the mouse for things like focusing windows or tapping dialogs. I'm very tempted to get one of those. Does anyone with experience of them know what the multi-monitor support is like? I have 3 screens side be side and one below, so quite a large range to cover that requires some head movement to go across all of them. Will it work with viewing over that wide of a space where I'm not always directly facing the primary screen?
