I didn't have a micro SD card, but did have a Bluetooth keyboard and mouse that were connected when I started the update. Disabled Bluetooth and tried again. Got the same DRIVER_POWER_STATE_FAILURE BSOD error at about 75% but this time, it auto rebooted and was able to move along and complete the install without further incident. After the first manual reboot post-upgrade, I got a similar error but it hasn't happened since (did 5-6 reboots). Bluetooth and WiFi are working, although the WiFi performance is degraded from time to time.
Biggest annoyances/bugs discovered:
1. Cortana auto launches and won't go away without a fight.
2. When dragging a tile with a finger, the tile refuses to drop in place and keeps floating even after you've moved away from the start screen to desktop or an app. It will usually disappear once the orientation is changed from portrait to landscape or vice versa. It happens with a mouse as well, but less frequently.
Overall, it's a fantastic build for tablets, especially smaller ones like Stream 7. Still some imperfections, but this is finally starting to come together.
Also updated an Alienware laptop (M11xR3) without issues.
