Are there any users of the following Powerbook using Logic with an external hard drive ? 1.5Ghz / ! GB / 80 GB (about 18 gig left now). I'm thinking of getting a FireWire drive but looking into what the best options/specs might be and if anyone has experience of making use of a similar setup. Many thanks ! P.S. Native Instruments are running a special offer is anyone is interested: http://www.native-instruments.com/index.php?id=niversaryoffers_us
