It's the coolest electric car on the market right now at a decent price. The other ones look like garbage. I'd place the Chevy Volt as second.
So, to rephrase your reply:
"It is so cool it is worth waiting for, versus the other ones which look so much like garbage, they aren't worth having right now."
That's not bad at all. The garbage-looking EVs are what essentially forced me down the route of hybrid.
However, the researcher and accountant in me has been surprised to discover that hybrids are, in fact, the best consumer proposition in this category by far and will probably continue to be for a while.
