. Without a system to play with I can't say for sure what is going on here. I fairly certain though that if you ran these systems side by side, that is a Mavericks machine and a Ubuntu machine, that the machine running Mavericks would last much longer. Let's face it Linux isn't a low power platform yet. Honestly it would be interesting to see if Michael could run a few tests to confirm my theory. Maybe run his benchmarking program until the battery dies a few times.
