Windows/Mac OS X: iTunes 10.3 beta is officially available, bringing with it a portion of the new iCloud features known as “iTunes in the Cloud”, but only the features that matter if you buy content from iTunes.
More specifically, this beta version of iTunes in the Cloud includes the Automatic Download feature, which, as the name implies, automatically downloads songs and books purchased from the iTunes store to all your Apple devices, ranging from the Mac to the iPad. You can also re-downloaded previous purchases (music, apps and books) using iTunes purchase history (without charge).
