Do you think it was as good as a factory-produced matte screen? While I was aware you can do this, I'm a little hesitant to do something which is an absolute minimum for usability, in case I'm not happy with the outcome. It feels a bit like having to install a keyboard on the laptop myself, because the laptop didn't come with one...
I honestly couldn't tell the difference. You lose some output and viewing angle, but you did so on the matte screen as well. I had it on for like 6 years and my wife still has hers on from 2011.
