Yeah, the lack of included chargers is a big thing to consider. I had my e2008 for a year with no home charging. I have paid for very little of my charging over that time. It’s probably my fault the monthly costs have gone up so much 
I’m looking to move in the near future and a big consideration is at home charging. I don’t care if it’s 3 pin, I just need to be able to charge at home. And that might make the downsides of Elmo moot.
Given the ever increasing prices, I think Onto ought to look at offering charging as an add-on too. Maybe leave it included in the “budget” cars with lower ranges, as that helps sell the idea of an all-in-one cost for a little city car. But for the bigger cars, the ones people may be charging at home and using motorway chargers, people are getting no benefit, but instead subsiding those of us who survive off of the included charging.
