So far I love it. I had to go to class immediately after it arrived in the mail so i just performed a restore from my prevouse phone, but now I've had a chance to tweak it a bit. I purchased a
Golla Air Wallet to go with it, but it's a bit tight. It is leather so it will stretch over time so that's fine. The bigger screen is definitely an improvement over the 435, and I'm happy with the performance with it. I thought I could use Nokia Drive+ but that seems to be a Lumina exclusive (which is kind of disappointing). I don't have a second cell number so I can't try out the dual-sim feature, but I got it tidied up so I don't just have 1, 1, 2, 2 on the home screen. I haven't put the screen protector on it, I can never get the bubbles out and I had already smudged it a little before thinking of putting the protector on.
Overall I'm perfectly happy with it and will use it for a while. Eventually (6-24 months) I might upgrade to a Continuum-compatible phone that I can also use as a laptop replacement, but in the mean time this is an awesome phone.
EDIT: It is now installing a second major update in a row... And I already dropped it, scuffing the frame on one side a little
