Not really a fair comparison since this was probably alpha-quality software, and the build they used was very likely build for that specific demonstration (that ok, went badly). Like the (in)famous first iPhone presentation where Steve Jobs had multiple iPhones and needed to exactly time when to change between them otherwise they would crash.
If you are going to live-demo your latest software to the world, you better make sure that the very limited functionality you are going to showcase actually works. Especially since you get to choose the interaction, and know all the conditions and hardware beforehand.
Is that legendary QC in the room with us right now?
