Has Boot Camp changed in Snow Leopard?

"Yes, @ $29 it's worth buying Snow Leopard, and I can name you two reasons :

Full support for Windows 7 (both x32 and x64) with Bootcamp 3.0
Improved battery life (probably with the updated drivers)

Are you referring to Windows 7 touchscreen multi-touch? In that case, the answer is no, Apple trackpads will not work with Windows 7 multi-touch functions. In fact, I think you are missing out on the whole point of multi-touch here."
