My GF had this phone and I actually liked it better than the Galaxy Nexus I had. Felt great in hand, was snappy, I never noticed lag. Battery was great for her, all she did was play games, not shoters or action games, facebook light browsing, lots of texting and calls. Would easily last all day for here with LTE on. Only con for me was the screen wasn't as crisp as the nexus, and size. Was a little small for me but she liked the size.
Also got the 4.2 update quick, faster then the Galaxy Nexus on Verzion.
