WHEE! eMac got delivered today!!! i'm a switcher. can't wait to take my lunch break to go play on it. wondering about the preinstalled os though.. should i wipe the disk and reinstall myself? or just leave it as is? would i "lose" anything by wiping? i just need to do my own installs to feel clean. p.s... how do you "install" mac software? just open a dmg and drag it into the apps folder? wow, i am new.
