As the owner of an 8 month old early-2013 rMBP 15", and especially as someone prone to new product envy, it's nice to see that the new models don't blow the old ones away in performance. I'm generally quite satisfied with the battery life on my existing computer, and Mavericks not only seems to have improved on this slightly (pending more extensive testing) but fixed a lot of the annoyances with this computer under Mountain Lion.
I'd ordinarily head straight for the "Waiting for Broadwell!" camp, but I'm happier with this computer than I have been with any other computer for quite some time.
