My laptop was running out of hard drive space, but now that I've offloaded some data onto our new Seagate 250GB FreeAgent drive, I have enough buffer space to download the SICP video lectures.
Once I move to Linux later this month I'll have to get the files off of the drive using ntfs-3g or the other ntfs driver and then format the external drive to XFS, then put them back. And even then I'm not sure how to share the drive with Michelle's Mac.
