iTunes just got an upgrade, getting things prepped for the DRM-free AAC sales as well as adding some new features. Dubbed iTunes Plus, the new version will allow you to either download DRM-encased files for the standard $0.99 or, for select songs, spend $1.29 on DRM-free songs.
In addition, iTunes is adding iTunes U, a section where you'll be able to download lectures and other materials from various universities around the country free of charge. It'll allow you to better yourself without all the pesky debt that goes along with going to a private, four-year institution. Soon, you'll be able to put "iTunes U" on your resume and people will know exactly what you're talking about. You might not get the job, but they'll know what you're talking about.
