Thought I'd share with you what features are working and not on my laptop (HP Elitebook 2540p) with Windows 8. It may apply to other laptops as well.

and Validity drivers
One thing that had me fooled for a while was how to power off the computer. The power button of course is linked to hibernation, which works well, but to shut down, I had to go to metro/start menu/whatever and then click sign out, then find the power symbol and choose shut down.
An easier way is to go to desktop (win+d) and press alt+f4, for the regular shut-down menu.
An even easier way, if you're too lazy for the keyboard, is a shortcut on the desktop. To a .cmd file that contains only "shutdown /s /t 0". It will shut down immediately, so be careful, you can change the switches to whatever is your taste.
Synaptics Touchpad
The people at Synaptics have released a new driver suite that supports Windows 8 mouse gestures (or touchpad gestures, if you will). Luckily, it also works with the touchpad in 2540p. Just download their drivers for Windows 8 and install, reboot and you're off.Right click the Synaptics icon in the system tray and go to "Touchpad properties" for a handy introduction to the gestures and switch on and off the different ones. In my experience they all work! Especially the three-finger scroll is helpful in modern/metro UI.
Happy Windows 8 install!
