I mostly use my ps3 as a Netflix machine now-a-days (new baby) and have been very frustrated with the PSN downtime since Netflix won't let you login to their service unless you are logged into PSN (for some reason). To me that means my TV has seen very little use and I get to watch shows on my 13" mac. :(

Overall I am very disappointed in having the PSN be so key to the ps3 experience while the PSN, to me, is pretty worthless and poor even when it is working.
