I try to use Win 8 but i think it was not so friendly and honestly it is time to have a Linux Desktop.
I chose Ubuntu and the setup, on the Toshiba P875-S7310, was easy and fast, after i installed an SSD HD and more 8 GB RAM.
The only thing that did not work was the LAN.
How to solve the problem :
sudo apt-get install linux-headers-generic build-essential
tar -xf compat-wireless-3.5.1-1-snpc.tar.bz2
sudo make install
sudo modprobe alx
Very nice Ubuntu 12 on my laptop :-)
