Sony tried to market the PS3 as a multimedia entertainment hub - in hindsight it was an idea ahead of its time, since that's what basically all Smart TVs are now - but the $700 price tag made it unattainable during the critical first year of sales.
it also launched with "install other OS" as a feature, which they removed later via an update.
Yeah I've heard about that, for certain applications they were a super cheap super computer. That's why I wish the official other OS support had been maintained - after it got dropped, support for it stopped getting worked on by the Linux community, imagine the wacky things they would have been able to do with it if support had never been dropped.
