Hi everyone, A little green when it comes to the upgrading of software and I think my skepticism stems from all the horrible MS updates which brings me to my dilemma. I never updated from Leopard to Snow Leopard (as I was advised by one of my close friends not too, because she felt it was a step backwards ). Been wanting to get Lion for a long time but apparently there are some programs that you need installed from SL to get Lion to function. (Please excuse the lack of "techy-talk", I'm a natural scientist). Can anyone offer some advice or a solution without having to fork out $29+ per iOS? Thanks in advance.
