I watched the demo from my Android. It was an awesome short and to the point presentation. Everything worked flawless, I could click on all the images that were taking you to the calendar, or the save your spot or shop and you could still hear McKinley talking.
Don't forget this pre lunch demo was for customers and not necessarily for investors.
People that will try to say or find something negative maybe they can direct their questions to the team so they can get a more appropriate response.
Also lunch arrived 30 minutes before the event.
