The Nexus 4 looks pretty good to me, although I don't know if I'd do much "reading" on it. It would go well with my Nexus 7 which I'm very happy with, and replace my old steam-driven, 2-year-old Android 2.1 starter phone.
Key features for me:
- competitive price
- unlocked (I don't sign contracts, preferring to pay-as-I-go)
- multi-band support gives me more choice among carriers
- prefer Google's "open" approach to H/W and S/W, over Apple's proprietary "walled garden"
