Works with ProTools/Logic/Live? (Score 1)

I'd love to hear anyone's experience using one of these systems with pro audio software. That's the only reason I need a faster machine than my little 2gHz Macbook...

Specifically, I have an Mbox2Pro & Apogee Duet (both firewire), PTLE 7.4.2, Live 5 (yeah i know), Logic Studio 8. Experience with any combination of these would be useful.

Thanks!
