Happy happy joy joy, the Zune upgrade software became available today!
All first-gen Zunes can now upgrade their firmware and gain the new capabilities that are offered in the second-generation Zunes, which will go on sale today.
Three cheers for wireless synchronization of files and podcast handling. (Well, the Zunes could always play back podcasts, but now the Zune software will actually manage your subscriptions for you.
I'm posting this as the final stages of the upgrade proceed. When everything's done, I'll be Very Pleased.
