Do yourself a favor, do not *ever* buy Sony. Their support is a joke, even at the enterprise level (which I've had to get support on) they are permanently banned from ever being on my recommendation list, unless they do something significant to turn themselves around with (not likely)
As an example, we had a system that died on us, was less than a year old, but because the system release date was more than a year ago, they based support requests on the system release date and not when we purchased the system, EVEN when we supplied them with the purchase date AND a system serial number (which they claim isn't in their system)
Sony's PC division treats you like scum. Don't ever buy from them.
