Aaaaah. 4WD. I'm a sedan kind of guy and I really want my electric car NOW (managed to hold off on getting a Roadster because a two-seater convertible is just not practical for me) so I'm getting an S. But I suspect the X, with 4WD, is what's going to sell to most of my friends and family who have the money. They are not as eager to go all-electric as I am, but still need the range, still live in a hilly part of the snowbelt with bad roads, and are more open to SUVs/minivans...
