Why change to Yosemite?
I have a 2009 iMac and reading through the requirements for installing Yosemite I note that many of Yosemite's features will not be supported by my Mac. I wonder therefore whether it would be worthwhile upgrading.
Has anyone in a similar position taken the plunge, and if so have you found it to be of benefit?
