I need help , i own at the moment the 233mhz iMac , it is really old and i am thinking of an upgrade , but i don't know what to choose; should i spend more but get expandibilty with the PowerMac, or spend less and get a perfect computer but most probably not last as long as the PowerMac and go for the iMac. I am not a person that needs a superfast computer , but it is just that with this iMac i have now , i have no more space on it to even upgrade to OS X, and i am afraid that if buy the iMac that in 5 years or so i will have the same problem that i have now or perhaps another problem such as slow processor etc. . If i were to buy the PowerMac then it would most probably last ALOT longer. Oh another question will the PPC 970 cost more than the current G4?
