The difference is still minuscule. £549 vs £469 is insignificant, especially when you can get a Nexus 4 for twice that difference (£159).
The 8GB N4 is £159. You can grab it from here https://play.google.com/store/devices/details/Nexus_4_8_GB?i...
Only thing I'm disappointed in is the camera, but that's why I have my Canon.
