Just and FYI, I just finished installing Mavericks and booted into it; the App store is automatically downloading the updated versions for me. I had installed them via DVD years ago and they were only available for purchase in the MAS. So I'm a happy camper, everything looks great so far.
That's really wonderful! I didn't expect a free upgrade since I purchased iWork back in 2009. It's totally acceptable for me that Apple charges me again, like Microsoft doesn't offer free Office 2013 to Office 2010 owners. However, Apple does! The only thing I can say is thank you apple!
