How Does Hearthstone Play on iPad?

Since I don't have an iPad myself, I'm curious how it feels to play on that platform. I'm also curious if anyone knows if it plays at all on iPhone (I would think that would be a bit much for the phone to try to handle all at once, but who knows?).

I was so disappointed to get that email from Blizzard offering a new pack for playing on iPad. If I had one, I'd totally do it. Sigh. I suppose I'll have to wait and pray for an Android port.

(goes back to twiddling thumbs while waiting)
