I have a 2008 iMac with 10.5.8 OS X, Intel 2 Core Duo, 2 GBs RAM. I can no longer play videos because I need to upgrade Flash Player, which I can't do with this operating system. I'm considering upgrading to Snow Leopard for about $20 with the goal of using this computer a couple more years. I have a video app and one game app on the computer. Will I lose them when I upgrade? I assume my 2 GBs of RAM will be enough for light use. Do you perceive any problems with this upgrade? Thanks in advance for you answers.
