OS X Mavericks notifications

Notifications are getting a slight refresh in OS X Mavericks. Apple announced today at WWDC 2013 that notifications would allow users to quickly leap into action without having to open apps first. This includes replying to incoming iMessages, sending canned responses to FaceTime requests, and even third-party apps will be able to offer a bit of interactivity. It's also worth noting that notifications are going to be synced across platforms, so you won't have to clear the same ones on your iPad that you already have on your Mac.

Mavericks is shaping up to be really nice, but honestly, it's hard not to be more excited about the iOS 7 stuff coming out of WWDC 2013. What do you guys think of Mavericks? Are you likely to be picking up the new Mac Pro or Macbook Air?
