  Works fine with some minor problems
What works:

Everything except the following items: wifi, mic and bluetooth.

What doesn't work:

-The driver for the wifi card is not in the kernel of this release.
-Internal mic doesn't work.
-Bluetooth seems to work, but won't detect any bluetooth device (tested with cell phone and keyboard).

What was done to make it work:

For the wifi driver, you have to compile it using git, following these commands:

sudo apt-get install linux-headers-generic build-essential git
git clone http://github.com/lwfinger/rtl8723be
cd rtl8723be
git checkout 604aa9058fb9e5bb1cf571c99989d081f8fc8b9
make
sudo make install
sudo modprobe rtl8723be

echo "options rtl8723be fwlps=0" | sudo tee /etc/modprobe.d/rtl8723be.conf
# Prevents the WiFi card from automatically sleeping and halting connection

Other approach is to install a newer kernel (this wifi card is supported in latest kernel) and try to run system. I found mine to run smoother with 3.13.0-29.
