On YouTube a long video demostrating HP Slate device running Windows 7 is spotted. The video gives a good overview of hardware and also shows the device booting into a fully usable copy of Windows 7. The device boots in 30 seconds, compared to iPad's 15 second boot time. The onscreen keyboard takes up approx 60% of the screen space and doesn't push any content above it to make it user friendly.
The physical dimensions and hardware on the slate look impressive however. The device is expected to have an 8.9" screen, two cameras (one for video and one for images) and will allow users to use a pen to write on the screen.
