Just upgraded from a 10gig, re-ripped from 160 AAC to 320 AAC= 16gig, 10 gigs of photos (thumbs and originals) and around 20gig of active audio and video backups from projects and students work that used to live on an old laCie 20gig portable...
Still got about 15gigs left, and I've got an album mix archiving next week which will free up around 5gig.
Oh yes, 60gigs is just fine, in fact, I'm waiting for the 120gig iPod. 😀
