Once I got a good wireless charger for my phone, I loved it - and now have one in each of my cars, at my desk, and on my nightstand. I have to put my phone down somewhere, so I put a charger everyplace that I would likely put it down. My phone is nearly always at 100% charge, and I never have to spend 30 seconds turning the micro-USB cable over and over trying to figure out what way gets it to plug into the phone. Yes, the wireless charger only charges my phone at a 3 hour rate, when my high-power phone charger will do it in one - but I don't care, my phone is always full. My high-power charger is in my travel bag for those quick fill-ups during a 45 minute layover between flights.
As soon as this system is available for my Model 3, I'll buy it. I drive my car 75 miles a day, and sleep at night. I really don't care if my car charges at 20 miles/hour or 30 miles hour - It'll start charging at 3 AM and be ready for me in the morning regardless. I won't have to move the UMC from my garage to my trunk if I'm going to drive a long distance. I won't have to hang the UMC from the ceiling so that I can easily plug it into the car (I need to park the 3 with the charging port facing the middle of the two-car garage; my other option is to lay the UMC on the floor and hope I don't drive over it...).
I do agree that a little bit of mechanization on the charger would be nice - rather than a wall-mount display that I have to pay attention to in order to park in precisely the right spot, a bit of motion capability in the charger to move itself to the right spot under the car would be nice. Six inches left and right, maybe 12 inches forward and back, maybe a bit of Z adjustability to better couple to the onboard coil and raise efficiency, would make the charger completely effortless. Even my wife could park that accurately without thinking too much about it. (Sorry, honey). But, then again, maybe it doesn't have to be very precise and the display isn't a concern.
