Hot: Asus updates touchpad driver for year old Zenbook, adds awesome Windows 8 support.
Asus hasn’t just updated every driver to work properly with Windows 8 for their Zenbook UX31e Ultrabook and updated the BIOS to support UEFI which causes the machine to cold boot into Windows 8 in under 6 seconds in my case, they have also added great gesture support for their glass-touchpad that makes up very well for the lacking touch support:
Swiping over the edges of the touch pad open the charms bar, the app bar and the Windows 8 task/app switcher. It works like a champ, I am very impressed.
Thanks, Asus.

will this driver be available for other ASUS laptops that are pre-loaded with windows 8?
I hope it will! Best thing is to check with ASUS via email or have a look if the driver is available from their download page for the desired model.
