I love my Sony desktop and laptop products -- and use a Nikon D1X camera with the compactflash -- my latest laptop is a new GRS700 with build-in DVD RW. I'm using it as a portable video editing station and love it. Also have Picturebook and 2 Sony desktops (love the Giga Pocket feature).
I have no Sony peripherals and use the laptops with Canon GL-1 and Digital Elph in addition to my Nikon. My peripherals are purchased based on best in class and functionality.
N0 problems with reliability or warranty (did buy the extended warranty for the laptops)and love the equipment for video work.
