Here too.
I am Using a 950XL and also need it for business. It sucks that there is no official app for me. And giving the data to any 3rd party developer is really a very bad thing. Teslas seems to get stolen verz easz if zou use the keyless system, giving all the data outside opens a second door....And it is also not a good idea to make a second mobile contract just for the car.. That sucks too.. I always thought Tesla would be very innovative, but in a few things they are running years behind, but their marketing is great
Better WLAN standards and so on would also be nice, but a working WindowsPhone App would make it easier to make a buying decision.
