To be fair, your Gameboy has a LOT less moving parts and intricate workings to go wrong internally than the PS3 or 360. I'm not condoning the systems breaking down or anything. I had a 360 in 2006, it broke down (not the RRoD, there was something wrong with the way the system was communicating with the AV cables) so I replaced it with an arcade version in 2009, kept my hard drive and had store credits so it only set me back about $140. I got a PS3 later that same year. My 360 broke down again in 2011 and I finally just let it go and sold it and all my games for it. My PS3 is still working fine. I play several large scale RPG's on it including Skyrim, and have never had any problems with it so I don't really know what to tell you friendo.
Is it possible that it's the gaming market itself is to blame for products having to be released before they're ready, or developers pushing things out as quickly as possible? Let's think about it, would a developer rather get bad PR from constantly delaying a game or get bad PR for having to release patches? Patches are forgivable because they give the impression that the company is trying to meet set deadlines for customers and they're still trying to improve the product even after release. Delays anger fans because it makes them feel like the rug has been pulled out from under their feet.
This is simply an analysis, not necessarily my opinions. I'd personally rather wait for the game/console to work like it's supposed to before I get my hands on it, but unfortunately that doesn't appear to be the case for most of the gaming community.
As far as your particular situation with Skyrim and your PS3, I don't know what to tell you man. It could be a faulty disc, it could be your system, it could just be bad luck with your purchases. There's no real way to know for sure. If it's the disc then maybe try to return it and exchange it for another one or something, I don't know. Sucks you're having such problems with it.
EDIT: Maybe stop buying Bethesda games if it bothers you this much? I think at this point you should know (and probably should've formulated this opinion before Skyrim) that it might not be a coincidence for your experiences with Bethesda games to be bad. Maybe just avoid the developer altogether if it's going to be a problem for you.
