I had my little iBook to nol (thank you my dear wife). I have not had the opportunity to test a USB or FW audio interface, but knowing the phones and office machines PC and Mac, I can say that within an hour of use can be aware of the quality the bte.
I will give more information about the audio when I could test it with an interface.
Two small BMOL:
- 256 MB of RAM is a bit short
- No audio input (unlike the powerbook)
