Guys, I don't think it's because of the dock, but I've got a big scratch/dent (1 mm large, 4 mm tall) on the lower right corner of the screen, just because I put it in my bag yesterday to show it to some co-workers. I thought it was dirt at first but it's not, it doesn't come off.
It's not a big deal, it's not noticeable when playing and it's definitely my fault for not buying a screen protector (currently waiting for me at a conbini next to my house, gonna stick it on as soon as I get home), but be careful. To compare, I have a Vita bought on day one with not a single scratch and I've been throwing it in my bag a lot. Same goes for my phone after a year of constant use.
Blame me as much as you want, but the screen is disappointingly delicate.
