I have been getting tempted to install the RTM on my home machine just so I can start playing around with the new OS. Unfortunately, Vista seems to have 'snuck up' on E-MU and I have their 1820M card installed for my music studio setup .
I am not sure what else Microsoft needed to do to get vendors ready for Vista and it is ridiculous that EMU doesn't have much to say about their failure to release drivers that are compatible with the RTM.
All the forums are fuming about their lax response to this.
So...maybe I'll hold off a bit longer.
