Considering we're at 10.9 right now, or a beta I think, it brings up a serous question for the future. Will Apple mac an OSXI or just continue with the OSX? What would they change? Will we loose our documents if we upgrade? Will it support older macs? Will we be able to run OSX programs, and maybe get a program to run OSXI programs on OSX? Or will we just go 10.10?
