For those of you who don't know, #rimlag is the term used to describe the PS3 lag issue in games with large save files. There was some discussion of it here, but http://www.gamesas.com/index.php?/topic/1303536-new-vegas-developer-comments-on-ps3-lag-issues/ hit the post limit and has not been continued. There's also discussion of it at http://www.eurogamer.net/articles/digitalfoundry-vs-ps3-skyrim-lag and http://www.neogaf.com/forum/showthread.php?t=454241 if you're interested in learning more.
The main thing to do at his point as a customer would be to document your issues and make Bethesda aware of them (politely, of course). Regardless of bugs or #rimlag or other issues, Skyrim is still a good game and could be an amazing game with one or two more comprehensive patches. Let's hope that an honest discussion about these issues will expedite those patches...
