Been on Mavericks for about a good week now. Was pretty much a painless move, the only problem I had was that at this moment After Effects CC is unsupported.

It's a real tangible performance boost though. Feels extremely snappy on my Retina Macbook Pro. Scrolling is faster and I went from 2,5 hours of battery life to 4,5 !

I was just about to say the same thing - it's stunning how much faster/smoother it is.

The new way Multi Display works is also much better than the old way, Full Screen Mode is actually really useful now.

You just can't span multiple monitors with a single window. I do like the improvements though. Moving the Dock to a different window by pulling the mouse below the bottom of the screen is taking some getting used to.

If that battery life improvement is representative of general use, it is another indicator that they really are pushing for energy efficiency. The first one, for me, was https://developer.apple.com/osx/whats-new/, where the top item for "develop for OS X Mavericks" is "Energy Saving", not any of the new libraries whose coolness one can demo in a few minutes.

Apple increased the available video memory on the retina machines from 768MB to 1GB. The difference is profound. I was concerned about being stuck with nothing but an HD4000 but I'm very content with everything now.

you get only 2.5 hours on MBP Retina !?!?

Maybe he's using Xcode

Who knows how many charge cycles it has been through.
