My Blu Win HD LTE arrives tomorrow but my Lumia 521 is running 10 .63 like a champ. Lots of previous updates had bugs like crashing restarting etc. This hopefully is the stable update we've been waiting for. Anyone else with the 520/521 with W10?

10586.63 is a little laggy on my 521, but, so much better than previous builds of W10M. Not the best phone for W10. I definitely recommend upgrading to 1G as 512mb will not handle the entire OS. My next phone will probably be the Surface phone if it's not mythology.

I'm just waiting for W10M to be released and then for Blu to push it out. There are quite a few features I like with W10M that my L521 has that my Blu doesn't. Oh well. The bigger brighter screen and speed make such a difference. If I would have waited, I would have just got my taxes back and went for the 950 or 950 XL.
