So, my friend bought a new MacBook, 2.0GHz C2D, 1GB RAM. I went over to check it out and was surprised by how fast it was opening apps, like iCal, iTunes, and iPhoto. I think Pages opened rather quickly also. Now, I have a MacBook 2.0GHz CD, 512MB RAM, and mine's been used for about a year, with a nice full calendar, and lots of photos and tunes. I was wondering what caused hers' to be so fast? The C2D, RAM, or that there's nothing really in those programs yet. I have been thinking of upgrading my RAM, and I think it's coming up to me needing to. Will I experience the same quickness?
