I only recently upgraded to OS X Mountain Lion and I was planning to upgrade to OS X Mavericks when it is released. I was thinking what’s $20 for an OS upgrade, right? And then came Apple’s announcement that Mavericks is going to be FREE. So yes, I’m definitely getting my second OS X upgrade in a year, make that half a year. Right away! As usual upgrading was easier than easy (don’t you just love the Mac?). It’s an incremental update to be sure but it does promise better battery life and improved memory, among others. I even regained around 5GBs of disk space (I regained around 5GB when I upgraded to Mountain Lion). Not bad for FREE ;)
