I managed to get my Nexus 4 in the first batch. Never had a screen protector. Carry it exclusively in my front pocket daily. Its there or on my desk, that's it. I have yet to see a scratch on the screen. Any screen protector I have ever seen looks like crap and makes the phone feel weird. Even if it meant scratching it, I would go without. Having said that, I do have some fine scratches on the back from setting it down on things (or at least that's my guess), but I really have never considered caring about that. Phones are tools, I'm not going to lose sleep over anything purely superficial.
