My next phone will be the iphone 5s updated from the iphone 4, i looked at the iphone 5s, Sony Xperia Z1 and the Nokia Lumina 1020 ( i have a 920 right now*i have 2 personal lines*) but the iphone 5s always comes out on top for the best overall device in size, and features i will use daily, not so much a fanboy but more of what suits my daily needs for a device i can carry comfortably all year round.
*update* loving new iphone5s 64gb now i need to record interesting images That happens in front of me
