After having had a play around with Windows 8 on a non-touchscreen laptop I'd personally say that having a touchscreen for using the Metro UI will be a necessity, as it quickly becomes a chore when using a touchpad/trackpad.

As for the Ultrabook itself - it appears to have quite a lovely understated look about it.  If you're showing off new/future products to the world though Acer, you might want to avoid letting apparent manufacturing defects get through the cracks (picture 1: the hinge).
