I watched them all, thanks for posting.
Remarkably blunt advice and observations from the key staff of PC World, which of course makes it's living off of Windows, and Windows based products. MS devotees will not be pleased, nor will corporate MS I would guess.
(The only painful part for most wanting to watch them, will be the Dell rap ad you have to watch prior to each session. Makes you want to run right out and buy a Hewlett Packard. Take the guy's advice above, and kill the sound until each video starts.)
