New Macbook + Live + Virus TI

[digitalgeist]

Anybody using one of the new Macbooks, Ableton Live and the TI? I'm switching to this setup on Wednesday (it will be my live rig at least) and would love to know if there's any problems worth noting.

I'm specifically wondering about say...sidechain implementation with Virus Control, trouble using more than one patch at a time in Live, audio hiccups, etc. I'm going to bump the Macbook to the max 4gb of ram asap, but 2gb should be robust enough at the start.
