I have had issues with iTunes 9.2.1 now for weeks. I have been unable to restore on iTunes as the restore goes to about 60% and will not proceed any further. I've worked with Apple support on this and together we have been unable to find an answer so maybe iTunes 10 will solve my issue. Note...I have tried restoring on my Macbook Pro literally dozens of times with the same results. I have completely removed iTune 9.2.1 and all its files and reinstalled and still have the same issue. I've tried logging in as a different user and still the same problem. But no problem restoring with other computers? So maybe iTunes 10 will be the answer.
