I intensely dislike Microsoft and Apple, pretty much equally. But not really because of their hardware. More because of their proprietary and monopolistic business practices. Which especially in the case of MS has almost nothing to do with the HW side of their business, because pretty much none of their HW products have come close to being in a potential monopoly situation.
I'm not liking the overly proprietary-centric way Sony is handling the whole PS3 hack situation, so they've gone down a little in my estimation. So if I had to pick a company I liked the least when it came specifically to gaming system HW I'd probably have to say Sony. But my dislike for them on the gaming HW side of things is small compared to MS and Apple on an overall basis.
I didn't vote, because I don't think the context of the question really fits my views.
