The playstation 2 is still the most successful console with 150million units sold ( http://en.wikipedia.org/wiki/List_of_best-selling_game_conso... ). I'd say to get figures like that you need to have had mainstream success.
I can't speak for all of their products, I only have a couple, but I've never had a reason to complain.
I'm not apologising for them, they really have screwed up with this security thing, but I think it's disingenuous to claim they've only made crap for the past 20 years when there are some very obvious exceptions.
