SL runs like crap. Before any of this other stuff, lets get the engine working better. If that was a priority rather than ediiting, SL wouldnt ben in the murky situation it is in now.
This looks like "nothing really changed, everything is fine" to me? Not sure i would expect them to publish any negative data though.
Be nice to see more third-party reports. Im new-ish to SL though and am not sure were to go for such info.
