RRoD lasted years, it had a failure rate 3 times what MS initially predicted, on the first series, and the first mobo redesign wasn't enough to solve it, neither could the successive ones, refurbishing faulty units instead of replacing them with new ones resulted in the same units often needing more than one repair, furtherly multiplying costs, only 360S with total redesign and complete switch to die-shrunk, low power main components solved it.
And luckily for Sony, MS must keep quiet and an extremely low profile (that is only letting its minions and astroturfers doing totally unofficially the dirty work on the net) trying to spin the PSN incident, otherwise it could become the next target of the hackers. Again, as XBL was already targeted by hackers several times, they even managed to hack Major Nelson's account (if they could hack high execs accounts, who could tell us they couldn't steal any sensible data of XBL users?).
This said, Sony should follow the MS way and hire real experts like Akamai to manage its public sites (ironic how load balancing, site mirroring, DDoS protection and many other important services are performed for MS using Open Source SW, often Linux and other GPL licensed ones that MS hates so much 
), and maybe also getting help for its internal network wouldn't hurt.
