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!

It seems the key initiative here is to improve adoption rates which is a sound strategy. As a developer, it's always a pleasure to write apps that only have to support the latest and greatest.

It would be a pretty big feat if the adoption rates for Mavericks came anywhere close to the adoption rates for iOS7.

Installed it on a Mac Mini (3rd gen i7) and after the install it sat on a blank screen (with mouse cursor), but a forced restart and all was perfect and everything is operating brilliantly. Fantastic treat that it is free.
