My stepdad, a former windows 98 user is totally excited about getting an ibook. he wants to get a 14inch model with a superdrive, because he does not want to pay 2500 for a 15'' albook. He wants to plug his guitar into the ibook to use in garage band. problem is, there isnt a line-in port on the ibook. (there is on the imac, why not the ibook???) I would like to hear from people who have used the imic and the people who have used a direct line in, and how their performance is. A loss of quality? is there no detectable difference? He can get a 14'' ibook with a superdrive, 60gb HD, bluetooth, and a bigger screen for $200 less than a 12'' powerbook similarly equipped. Will the imic work well enough to warrent the ibook? or should he shell out for a powerbook?
