Recording On Ibook G4, is it enough just for recording? Options

[parubio]

I'm planning to record demos and live performances and now that iBooks come with a G4 and are cheaper than PowerBooks I've considered to buy one. I only need it to record (no more than 16 tracks at a time, normally I'll record 8 tracks), for mixing and editing I'll use a PowerMac G4 1'25GHz I own.

Is an iBook enogh for recording purposes? (Note: I'll use either a Digi002 or a Motu 896, with independent Focusrite pre's)

Thanks a lot.
