I have recently bought an SZ3 but have now noticed that sony has released the SZ4 which runs vista as standard.
I wanted to know if there was any difference between my model and the new one, which there doesnt appear to be -- ESP in regards to the the graphics card (eg type and amount of RAM).
If the graphics card is different -- is it possible to upgrade my graphics card -- as I am anxious to run a graphics hungry system like vista.
