The thing that got me started thinking about leaving it open was the bad update they did last week where it didn't work on the PC, which is the platform I use. But I also don't like the fact that it starts so slowly, particularly if there is an update. Which also may be a PC problem, but since that's the platform I use it affects me.
When I was searching around for the answer to this question, I found out you can turn on background updating for the pc if you want it. I might try it.
