The TiBook is used for documents on the couch, the iMac G3 is used for classic Mac OS games, the iMac G5 is used for storing and editing music and videos, the MacBook Pro is for gaming, internet browsing, and basically everything, and the Mac Clone is just there for backing up the iMac G3, and has a bunch of really old games on it.
Even though the Mac Clone's specs look better then the iMac G3, it is a lot slower then it because the PowerPC chip isn't a true G3. Plus, the processor is having troubles with heat since it's been overclocked up to 667 MHZ from about 2000 to about 2004 then the computer started smoking so I downclocked it to 467 MHZ. The original speed was 210 MHZ.
