It's stiff, pretty cheap, US made, race-worthy and can still be used for the odd century. What's not to like? I just bought mine b/c people told me to. Sometimes people are right

Cannondale seems to have perfected the Alu frame science.

For the price its better component-wise than others in it's class as well.

It's not a Trek or a Spec. As in, it's not so big that people hate it but not so small that's its exclusive. It fits in a good spot.

Pretty much all I can think of.
