Anyone upgrade to Windows 10?

I am running the latest Redstone build on mine right now on my device and its performing okay. I will mostly roll back to 10586 today because the SkypeUWP app is still not stable enough for Skyping.
 
I like Windows 10 on my tablet, and find the improved apps throughout the OS to be worth the upgrade from 8.1. Although on the current 14328 Redstone build my PC is crashing on wake from sleep, with and without the WiFi drivers installed, so I am going to try rolling back to a more stable build today...
 
I have 2 dell venue 8 Pro tablets that are running Windows 10 Pro and they work just as well as when they ran windows 8 Pro
