Loaded the phone w SwiftKey, disabled a bunch of apps, installed Nova launcher, awesome phone.. Took a while to customise everything back but it's fast and nice... Coming from the z2 the performance isn't much better, but there were some areas where I wasn't able to get to it completely like setting the wallpaper when I view a picture in the gallery, however I'm suspecting it could be due to an application or two which I could have disabled
The extra real estate is sweet too, not forgetting the higher screen resolution makes Flickr pictures all the better
