Awesome graph, cmoulder! And yeah, thinness makes up for the lower conductivity. So it's mostly price vs. weight, as with so many other things.
I did notice that Al pots seemed far more rigid in the stores than the thinner Ti ones. There was also a quip about Ti superiority that stuck with me, perhaps said tongue in cheek, but it was something along the lines of, "Your Al pot may not last 300 years; it may only last 30!" And if our leisure hours had a price tag, we'd no doubt be spending hundreds of dollars trying to figure out if an extra $30-$50 in pot cost is worth it.
But as you say, heat conductivity - in a practical sense, boil times - isn't a deciding factor. Other things may be (even heating, price, weight, durability, etc) but not boil times.
I also agree with the prior poster, Jetboils are amazingly fast. They're also pricey ... but time is money, right? Or is it not in leisure time? I guess everyone has to make that call for themselves in some way, usu. implicitly.
