But I know nothing of it a friend just told me that the main difference between the new mac mini and the previous version is that it has a new kind of RAM in it. Now I bought the most expensive model of the previous version about half a year ago, I think. My problem is that sometimes a browser or app will freeze for a little while (nothing major though) and the mouse shows that load icon. Also when I try and play a high definition movie on it I have to shut down any other app that is running or the picture will lag. I should mention that I already bought 4 GB of RAM some months ago, because the standard version only had 2. So should I get the new kind - will it help and make things faster? Or is it more the processor's fault?
