So I've never owned a mac computer before but after enjoying my iphone 4 and ipad 3g I think I'm jumping ship from windows. I just have a few questions and I'd appreciate any answers I could get. Will the base model be sufficient for my needs? Mainly going to be web browsing and using it as a media station with iTunes. The only thing I'm not sure of is ripping blu-rays. How long would it take to do a 1080p rip on the base model iMac and would the base model be sufficient enough to play back these rips? I'm currently having issues on my hp laptop even playing back 720p blu-ray rips.
