Not heard anything about a 8700. Where did you hear this?
With regards to the CPU, I can only think of 2 reasons:
1. Dell can't get hold of any 2.4GHz CPU's
2. They run far too warm in the Vostro. The XPS M1710 can be built with a 2.33GHz CPU, but its primarily a gaming laptop and has sufficient cooling.

And i know the Vostro 1700 has the 2.4Ghz...guess it runs too hot for the 1500, hmm.
