I thought it would be but now that I have bought it I am worried I have never used a Mac and I do not have it yet. I just want to use it for iphone development. It has the Intel Core 2 Duo but only 2ghz, not the 2.16. Is that going to make a huge difference? It only has 1gb ram and I'm fine with upgrading it. I think I can upgrade it to 4gbs (2 sticks)? It has Mac OS X 10.5, Leopard. This is the part I don't understand. I know there are higher versions but do you have to pay for a higher version or is it just an update? From what I understand I'll be fine with 10.5. The hard drive is only 80gb. Will I also need to upgrade that?
