Battery Life when live recording W/Mbox live

[Paver]

Hi, just wondering how much time you guys are getting typically while recording live 2 track into a powerbook or ibook, using phantom power.Can I expect 90 minutes or more? I'm thinking of picking up a 12" powerbook or perhaps an ibook.
Regards

I'm working with a client right now who's got an Mbox and a PC laptop and it drains the battery FAST. I'd recommend always having the computer plugged into an outlet when working with Mbox - especially with phantom power.

Chris is right. I just got rid of my Mbox and Ibook but I used that combo for over a year. The Mbox drain the battery really fast. I think I couldn't get more than a hour and half using the Ibooks battery with a full charge. Once I brought my Ibook to tech rehearsal for a show I was working on, without remebering to bring my power adapter, when my battery died sortly after rehearsal started boy did I feel like schmuck.
