I just ordered my Pi 2B. I'll give 10 a go on it when it becomes available.

I received my Pi2 B last week. You'll need to sign up as a Windows IoT (Internet of Things) Developer to be able to get the version of Win 10 that will run on the Pi2 when it becomes available. It's not clear exactly what this version of Win 10 will look like and what features it will have but it's a safe bet that it will NOT be the full blown consumer edition that we see in the Win 10 TP. MS hasn't said when this version will be available but only says "in the coming months".

I've already signed up for IoT. Being an ARM processor, I already know it won't be the full meal deal. More like Windows RT or Windows phone I would think. I have read it will come with developer tools rolled in. I already have a Pi B+, getting a 2 B was a no brainer. Bigger better faster. Well not bigger physically, but the amount of RAM on board has gotten bigger.
