iCloud functionality available today

So I found it confusing to figure out what is and what isn’t available today. Here’s what I have been able to figure out:

1. On the iPhone/iPad/Touch – in the “App Store” app, there is a new “Purchased” tab (along the bottom) where you can get any of the apps you have purchased before with your iTunes account, onto your device without syncing with desktop iTunes.

2. On the iPhone/iPad/Touch – in the “iTunes” app, there is a new “Purchased” tab (along the bottom) where you can get any of the music you have purchased before with your iTunes account, onto your device without syncing with desktop iTunes.

Now there is one additional item that was supposed to be available and is not yet, at least for me. That is iTunes 10.3, which will enable similar “Purchased” music (and some book management functionality?) for Macs and PCs.
