Is Mac Mini better than G4 and G5s? If so, is Mac Mini with Intel Core Solo good, or only Duo? Is there a huge difference between the two? 1.44 GHZ, 1.5 GHZ, 1.66 GHZ, 1.8 GHZ, etc... obviously there's a difference between those 4, but is the difference ALOT, or just barely noticable. And please note I'm a mac noob and I'd only use this for Browsing internet, listening to music, watching videos, and probably using Photoshop.
