Hi: my 20" is my first Mac, so I have no frame of reference, other than PC's... so maybe you can help... Everyone on here alweays seems to talk about how fast the intel iMacs are, blah blah blah... That is not my experience so far. Finder (which is Universal, right?) opens right up, but when you start getting down into some directories, it may take 5 seconds or more to display... I had two bvrowsers open (FF or Safari, I forgot- maybe both...), and I was dragging some text from one into a form on the other, and the computer ran 1/2 to 1 second behind me. Just enough to be incredibnly annoying! I notice when cutting and pasting, I see the menu bar flash, like it's running extra steps to accmplish a cut n' paste. Right now, I only have the base 512m card, should upgrade soon. I know mem should make things better, but I am curious what others thought- will mem help these, or is this really fast for a Mac?
