As a new handset, I’d love to play with a Jolla/Sailfish phone… The OS looks really beautiful and interesting, minimalist concept and battery life appeal to me, but apparently the thing doesn’t support US 3G/LTE bands and is generally very beta.
Might also try out the Sony Experia Z1-Compact phone. Also not available in the US, but it seems to be compatible with T-Mo’s US network, so I could probably get one that fell from a truck onto EBay…
