Ban, I also had the vpcz11 and one thing i didn't like was that it got hot after long usage(even on a zalman cooler), you should go test the instore unit and make it play some media for about 10 mins or something comparable to what you need to use it for(bring it on a usb stick
. Don't get me wrong its a great machine and i loved the sh*t out of it but as we all know any prolonged heat will kill the life of any electronics. Just my 2cents. Good luck on the buy!
