Th main use I have put it to is to occasionally check how much memory particular sites are gobbling up if I leave them open in a tab. Before the latest update, memory leaks gradually ate into my memory - increasing 10% or thereabouts every 4 hours. Since I tended to leave them open for days sometimes, it progressed to the point where my machine would hang or run VERY slowly. Now the memory leak problem seems to be solved or at least minimised.
I expect real techies get much more use out of it, but it served a purpose for me (amateur techie).
