your teacher is right trust him
after the slot loading iMac g3 the eMac is the best AIO computer apple has ever produced
the new ones might be faster , but just to big and to fragile
the emac is well made and heavy and looks rugged and at the same time just beautiful , and with it you get a perfect display
no dead pixel , no stripes, no pressure marks ( and i don't refer to the problems with the latest iMacs 27" ) just look on ebay uk and ebay .com and other ebay sites worldwide and look how many faulty eMacs are listed and compare with how many faulty imac g5 and imac core duo and core 2 duo are listed most of them with screen trouble , they didn't build them to last
thats why i don't consider the newer imac's worth buying used ,faster processor doesnt help if the screen doesn't show a proper picture or none at all and is more expensive to replace then the value of the whole computer , ok some might cry out now that theirs is perfect , but for how long? when even new imacs with up to 7 dead pixels ? are no argument for replacement ? ....i dont like gambling , i stay safe with the eMac
and for all friend of the iMac G4 dont worry yours is not a computer its a design icon
so its worth to replace a faulty screen at any cost
