I cant imagine buying a non-LTE phone today. I currently have the HSPA N4 and after playin with a couple LTE phones, its almost night and day. It feel more like I'm on wifi than a cellular wan. HSPA in Chicago barely gets me 5mbps with lots of latency and this weird 2-5 second lag where the request is made but no data is sent.
LTE's responsiveness, even if its at the same 5mbps bandwidth, is something of game changer.
With the nexus 5 at $350 right now, not sure why I would bother with either.
