I have been debating to switch to mac for a few years now, and After having so many issues recently with my pc, I finally decided to make the switch, got my self a basic Mac Mini 2.0 Ghz 1gb RAM 120 HDD last Friday. 1. I have a few questions. When I look in my aplications folder, at the bottom it says I only have 80 gigs of my 120 available. Where did the other 40 go? I'm sure a lot of is used by the OS, but 50 gigs? I only have a few pictures in iPhoto, and downloaded a few free applications. Can anyone shed some light? 2. I've been using iMovie and love it. But I notice that a takes a bit for it to import and export video clips. I created a slide show and when I added a 9min video clip it just dragged. Will upgrading to 4gb of ram help with this? 3. Is there an easy way to see what's using my memory? I love my mac mini! Thanks for the help and please be nice, since I know nothing about mac.
