1.- Why not? it's good
2.- I updated to 10.5.A.0.230 and then used towelroot and I have root, so yeah it's working.
3.- I can't really tell; got my phone less than a week ago so I didn't tried any of the older FW/Android versions. The first thing I did was update to the latest FW
I would say go for it and update it. It's working perfect for me and Inmersive Mode is amazing!
