Hi All- I'm thinking about upgrading to Mavericks and I was wondering if you can help me answer the following Q. 1) Is the upgrade worthwhile now that the first patches for the OS is out? 2) If I download the new version of iWorks from MAS, can I still keep my older versions (CD) installed? 3) Will upgrading to Mavericks mess up or replace the host files I edited in Mountain Lion? Thanks all! Also, Merry Xmas and Happy NY!
