How is the 15025 working out for your HTC m8? I'm sitting on Redstone 1 at 10.0.14393.67 and afraid to move on since it's my daily driver... I originally had my m8 (on AT&T - used registry edits to mimic Lumia 735 and get from 8.1 ver2 to the 10 preview) set to fast ring and flew past the 10.0.14393.67, but quickly got caught in a failure-to-fully-boot loop, so I had to throw my hands up and start over...
The version I'm on is pretty solid for my m8, only a few crashes when using heavy resource apps like the camera, people hub (I have a crap ton of contacts), and forgetting to clear multitasking building up. I've cleaned out all my old 8.1 apps and started fresh from the win10 app store since opening those caused of a lot of crashes.
Is it really that much better on the other side of Redstone (going to 2)? What makes it worth opening up my ring setting again to move forward?
