Lots of news coming out of Macworld, of course, but this one caught my eye: Seagate has announced Mac compatibility with the software for its OneTouch III Mini line of portable USB hard drives. The software offers security (password protection) and standard Backup features -- i.e. schedule backups or utilize the OneTouch button -- but also a great-looking folder-based Sync option: select your Music folder, for instance, on one Mac, back it up on the drive and sync it with the Music folder on another. It's even possible to modify the files on the drive directly, and sync the changes back to your machine.
The drives come in 80GB ($129), 120GB ($169), and 160GB ($229) capacities and are available now. Check out their website for more details, and check TUAW in the near future for a full review.
