Nexus 5 is a huge step up from Nexus 4. Better build quality & looks, LTE, and KitKat.
And who can argue with stock Android with NO BLOATWARE? Sounds like the phone for me.
I'd LOVE to win one!!! I think the white would look so sexy. Of course, if that's taken the black is fine too. I've never had a Nexus before so PLEASE lay it on me!!!! :-*
