I, too, have ordered one in California and am trying to decide on which EVSE (charging station) to get. From what I can tell, the BMW Wallbox Pure doesn't provide any functionality over other EVSEs like the highly-rated Clipper Creek, Aerovironment and others. It seems that all the iRemote functions will work no matter what EVSE your using. The problem is it's a big hunker, albeit pretty, yet several of the others are much smaller. The only thing I haven't been able to determine is the Wallbox's output rating for the US. Most of the other EVSEs are rated at 30A max, which will come a little short of taking full advantage of the i3's 7.4kW on-board charger. If the Wallbox can handle 32A and pump out 7.4kW, then it may be worth the extra size and unknowr reliability risk to be able to charge a little faster (or you can buy another company's EVSE rated at 40A).
I see that there is or will be a Wallbox Pro available, which has a touch screen to access additional info and functionality, but I haven't seen any details on it.
