It didn't take long. Aluminum kneeboards for the iPad are here. Pictures at www.forpilotsonly.com. Flip over "door" gives you a writing surface and is short enough not to get in the way of the yoke. Inside is padded with an opening for the iPad controls and charger. It fits comfortably on your leg with a standard elastic strap.
Update: ForPilotsOnly is now releasing a new molded kneeboard for the iPad. Pictures and pre-order special pricing is at:
