I love my macbook.
ADIUM ............. if you chat under different screen names or have chat accounts with different programs...ie yahoo msgr/AOL/etc. It lets you log into multiple servers under multiple screen names at the same time. The only draw back to it is it doesn't support voice or video yet.
Mac the ripper ........... is a dvd burning software. It lets you burn any dvd to hard drive or to ..... where ever you want, to include blank circular video disks...lol
VLC ............... allows you to play any formated video including windows formate.
Find a good copy of microsoft office. I have 2004
Turret wars ............ is a good low res game to waste time.
