I'm with you, hotels are instant to book while airbnbs you have to correspond and have this whole personal experience, no thanks. Also I can't in good conscious support them after having to buzz in a drunk airbnber at 2AM who was ringing every single apartment in my building because they lost their key.
Likewise, Cabs are much cheaper and faster to grab than Ubers in my NYC neighborhood (east village). Don't believe the hype...
