Update #1: Samsung has released Windows 8 drivers to support better touch and rotation with Windows 8. Please go download them now!
Update #2: There is a forum post outlining how to get WiDi (wireless display) working in Windows 8. Since I don't have a WiDi endpoint and thus can't test this, I can't really speak to the effectiveness of the instructions.
This is an update to my previous post about running Windows 8 Developer Preview on the Samsung Series 7 Slate. Until we get Windows 8 logo'd hardware, I believe this to be the best developer device for doing early explorations into Windows 8 development on.
That said, this is still beta-level software. Tread carefully. :)
