G4 / Pc With Protools And Cubase Options

[fatfil]

Hey everyone I'm a newbie to this forum, i'v been working with PC's and Cubase for many years,

after recently having worked on Mac's with Protools, I noticed that for me, both platforms are really good for different things.

I'm thinking of buying a powerbook, and i was wondering if I can run both protools and cubase SX (with a F-410) or if it's best to keep cubase and my f-410 thru my pc laptop and protools thru the mac.

Basically i like sequencing through Cubase and Digital Audio recording through protools.

Any ideas are appreciated..

cheers.
