It seems to me that above all else, LL needs to have a strong handle on crash rates.
Without this, performance and functionality are pointless unless you can log in and stay in SecondLife.
That said, what are the clear plans to get a full coverage of every permutation of OS, Patch Level, Driver Version, and Graphics Hardware going through a full suite of graphic effects (lighting, particles, client rotations & sound, rezzing, prim torture, etc etc).
Can LL publish a full list of system configurations they have seen attempting to log into the main grid?
Could we check off one by one each system configurations (or at least the 80% main ones) and whether or not each configuration has gone through a full suite of graphics stress testing?
A lot of us could try to drag our friends into the preview grids, depending on their particular hardware configurations. I could send an IM out saying "Anyone with this version of ATI Radeon, can you IM me back?" and that sort of thing.
I personally am a bit worried that we're going into summer with 1.7 (peak time for SL) and another jump in crash rates does not do anyone any good.
