Upgraded iTunes to 10.3 on my Mac and was delighted to find that I could pull down music purchased on my iPhone directly onto my Mac:
And yes, there was a "Download All" button below the screenshot that I used in this case.
Similarly, I pulled down a variety of purchased music directly onto my iPad that I had not sync'd via the computer-based iTunes before.
If this is a true preview of how seamless iCloud is going to make the user experience once it comes out this fall, I'm really looking forward to it!
