It should be worth noting that if you run Adobe's Creative Suite (version 6 and below), it has some compatibility problems for a number of users, including me[1] while running it on Mavericks. If your business depends on this software, I would advise you to wait for a few more months until these bugs are fixed. Overall, very excited!
