Pros
Power management/Sleep work normally for the most part. The only difference from actual Apple hardware, is that you need to tap the power button to wake from sleep, as opposed to screen lid, mouse movement or space tap. Fans work properly, same as on a macbook. They kick in on heavy CPU usage and high temps. However, I must say, the device keeps very cool most of the time. Other pluses include Portability & Price. The 6 cell battery gets you around 5 hours of usage.
Working perfectly:
* Core image
* Core animation
* Core audio
* Video Out & Graphics in general
* Wired Ethernet
* Webcam
* Internal Speakers
* USB
* SD Card Slot
* Sleep
* Bluetooth
* Wifi
* TouchPad
* Function Keys
Cons
Not able do perform Major OS point upgrades. There is no support for this. Warranty becomes Void. You are totally on your own. Web Cam, Wifi & Bluetooth, need to be activated via the function keys before the OS will see them (very PC like). The trackpad feels a little clunky, however I prefer a small mouse (wired or bluetooth). If you try to save a few dollars by going with the 3 cell battery, you will only get 2 hours of usage.
Not working:
* Internal Microphone
* Microphone port
* Headset port
