We know chances are you've probably got better things to read about than the PS3's next firmware, but this one proves to have some fun goodies sure to catch a few eyes. Namely, you've got that Folding@home client, as expected (did you join Team Engadget? Didya?), background downloads (finally!), Remote Play for wired 20GB PS3s -- all four of them out there -- and an onscreen keyboard á la the Wii, except, you know, different because it's PS3. Look out for that to drop on March 22nd (in Japan, anyway), suspiciously near the Euro launch date.
