Trust me. It took me a looong time to convince myself to even try it. It all seems so counterintuitive. Even the first couple of times I tried it, besides the noticable improvement in the final finish, I still wasn't sure I liked doing it. However, after 3-4 times, I really got the process down, and discovered that it actually took me less time. I would say that the wheels still take about the same time, but the main body goes so fast. I really can't explain the difference - perhaps it's related to not performing a second rinse, dragging the hose around the car, etc. I keep several towels on my shoulders as well, so once I wash a panel, I have the towels immediately available for drying.
One process you need to figure in is washing rags immediately afterwards. I toss them in the washer with a little Rags to Riches, and let them run. This is something you probably need to do with regular washing as well if you dry with microfiber, but it may be new if coming from a chamois.
There are lots of videos on rinseless washing on YouTube (The Rag Company, Obsessed Garage, Pan the Organizer) to help you better understand it before trying it. That said, (like the Emira) this is probably not for everyone. But it is definitely game changing for some of us.
