I uses SLGO with my PC. It works wonderfully. I don't have the best graphics card, but with SLGO I am able to see graphics at the Ultra level. It rocks. I don't crash half as much and when other are experiencing lag, normally I'm not.
No I do not work for SLGO but I am very happy to have it. Things are so much more beautiful in SL.
All you do is log into the program, it connects to the cloud, then log into the SL or Firestorm viewer and you're set. If you need your chat logs, you have to retrieve them from the cloud. That is the one thing I noticed. One drawback I am trying to figure out is how to view movie streams. This does not look possible due to using the viewer on the cloud versus the one on your computer. Anyway, it still has been advantageous for me to use.
