Horizon has been working long and hard on integrating important info into the cockpit. You won't find a more heads up regional carrier. Yeh, they've been flying with HUD for years.
I know they had a contract with an EFB maker that went TU two years ago, and were integrating ground based Wx radar and other info into the EFB.
If Horizon does it, you can bet it's the right thing to do.
