You know, this is interesting.. I just installed Windows 7 on the 8930, which has the Acer Crystal Eye webcam too, didn't check whether it works or not (I just installed windows, no speciality drivers
from the Acer site).
Today, after booting up Skype, I went into the video call section, and lo' and behold, the webcam works without a flinch!
I suspect that either Windows 7 has a good enough driver
for the webcam already, or that it finds the right ones later..
I'll add a screencut showing the drivers installed on the HD CrystalEye.
