I don't know about anyone else, but I think that the size of the Nexus 4 is too big at 4.7". I was hoping for a 4" to 4.3" screen, but Google have really pushed for that extra big handset.
Glad I'm not the only one.
To me it's just silly to call a 4.7" phone the Nexus 4. They should round to the closest whole number and call it the Nexus 5 instead.
It's called "Nexus 4" because it is the fourth Nexus phone (after Nexus One, Nexus S, Galaxy Nexus), not because of the size.
