But if one wishes to upgrade from a 520, they should upgrade to a 630/635. As much of a turd the 520 feels like after using...any other Lumia, its still a killer deal for a smartphone. I'm sure the redesign, though minor as it seems, make the baby Lumia a better experience.
The price is lower in the USA because of Carrier subsidies. AT&T, even T*Mobile has far more customers than Orange or O2. Our mobile plans general cost more as well. Thus, we almost never buy devices unlocked/SIM free, which does cost more.
