Worse, worse and even more worse with each version

If we ALL had identical systems, connections etc etc... and there were issues with SL, than that would be the culprit, but this is the real world. Some systems may cope better than others, SIMs servers are not equal in their performances or abilities, some host bad/corrupted textures etc.. so its dependant on many elements whether you have a good or bad experience overall, or just the odd day here or there. The variables are astronomical.
