Despite the shaky connection, the iPad performed admirably. After starting the Luna Display software on the Mac and an iPad, they were up and running with the iPad acting as a second display. The Astro HQ team pulled out a tiny nubbin and connected it to a MacBook Pro’s USB-C port. Hotel WiFi is notoriously bad and the Marriott’s, which was ambushed by thousands of WWDC attendees, was holding up, but spotty. I sat down with the Astro HQ team for a demonstration of an upcoming hardware product called the Luna Display, a tiny dongle that turns an iPad into a wireless second display for a Mac.

The lobby was crammed full of developers and other people tapping away on Macs and iOS devices connected to the hotel’s WiFi. In June, I sat in the crowded lobby of the San Jose Marriott hotel just across from the convention center where WWDC was being held.
