Apple's impressive new iPad Pro 12.9-inch model could be very hard to find on launch according to Bloomberg. Its vaunted mini-LED-based display is said to be behind the supply constraints due to difficulties with producing the new panels.

This is unfortunately not surprising. Such a new and different display tech was bound to have issues, and I'm sure everything going on with tech supply in general isn't helping. I do hope they're able to improve things quickly, not because I want one, but because I'm hopeful for mini-LED technology in general and want to see it come down in price.
