You should. I preordered with a case, but it still hasn't come in yet to B&H, so I'm on my own for now. In that case,I think that you would be fine. Just be careful when it comes to putting it on tables/desks without some kind of cushion. Like you, I have never broken a screen and I have no intentions on doing so. These little scratches are silly.
The auto screen brightness is very random sometimes, it can really go from high(not blinding, just somewhere around 60%) to 20%. I don't usually set it to high, but so far, it's been alright.
