Buick offers this one one of their models.
I think it's an excellent idea.

It'd be nice if that were true, but when you're in a place that has harsh winters, you'd go through dozens of cans of that every year and you'd have to use it every time you want to go anywhere. Sometimes I have to stop and re-scrape the window more than once because it frosts back over before I get down the block. When you're in a hurry and it's cold outside, heated washer fluid is exactly what the doctor ordered. Once you raise the temperature of the glass, it won't frost over again, and heated fluid is a lot quicker than waiting for the defroster to heat up.
I don't see the need for 150*F fluid, though. ~75-ish ought to melt water just fine without risking a windshield.
