When I installed Premiere Pro CC 2014, it did not replace Premiere Pro CC, its predecessor; you'd think that a so-called cloud-based application would simply update itself. Adobe says this was a conscious decision made because projects that have been created or even opened and then saved in Premiere Pro CC 2014 cannot be opened in Premiere Pro CC, and certainly not in Premiere Pro CS6, if you're clinging to that version. See a features comparison of Premiere Pro versions. The only difference between the Mac and Windows versions of Premiere Pro CC 2014 is that you can't encode to Apple's ProRes codec on Windows machines.
I don't have any significant gripes about Premiere Pro CC 2014, but even if I did, it's possible that they might be addressed as soon as I opened my mouth: The application received significant updates in June, July, and December 2013, and again in June 2014 (this release). It's a cloud application that doesn't actually live in the cloud or provide access to cloud-based processing power, but it is certainly reaping the benefits of a cloud application's update schedule.
