For everyone person looking to dump their fairing, there is another wanting to fit one!
I personally come down on the side of not having one, but then I use my bike recreationally, even when driving to work. If it was cold and wet, I would leave it at home.
I too think that all the weight would compromise the performance too much.
If it was a daily driver and I had some distance to cover, I might be tempted to go down that route......
