Apple to Charge Upgrade Fees?

News.com reports that Apple may start chargning for upgrades to some of its iApps:

According to sources familiar with the plans, Apple is expected to announce at the Macworld Expo in San Francisco on Tuesday that consumers will have to pay for new versions of iDVD, iPhoto and iMovie, which will be sold together as a bundle. Previously, Apple had offered upgrades to its digital media, or "i" applications, for free.

Historically, Apple has charged for the last iMovie upgrade (2.0), as well as a $19.95 shipping/handling fee for iDVD 2.

First hints of this particular rumor can be found in this Appleinsider thread.
