Pogo Connect + iPad mini?
The only caveat is that the mini was not supported in early versions of the sdk, so almost all of the apps need to be updated before you can use them. That being said, Procreate works great (please add palm rejection), so the only app that I am really hoping gets updated soon is Paper.
I also had a very slight defect with my stylus, and even though it in no way prevented use of the device, their support team was incredibly helpful, and got me a replacement right away. I can't say enough good things about their support staff.
