Tablets are the way to go, IMHO. My work laptop is loaded with all sorts of product demo software but it's so easy to just hand someone my ipad (cellular data) and let them swipe around to their hearts' content, make notes with the apple pencil, etc. The laptop takes time to boot up, passwords, logins, tether to phone, etc. When it comes to the mobile experience, I think a tablet is the experience folks are asking for.
