I'm finally upgrading my old iBook G4 800Mhz.. Getting a MacBook C2D 2Ghz today via FedEx! Just wondering if you all have any tips, like should I reformat and reinstall OS right away? Any suggestions of must-have software? Do I need to run something to help keep the machine at a lower temp? etc???? Thanks. Oh, and is the MacBook going to feel so much faster than my iBook that I won't feel too sick about the $h1ty integrated graphics? Or will I be throwing up all night? I'm not really a gamer but would like to do Google Earth, X-Plane, and light iMovie/Final Cut Express stuff. I guess I'll know in about an hour.
