I am looking at buying a Ibook g3 for surfing the web, listening to music... The specs are 30gb harddrive, 800mhz g3, air port wifi , 128mb of ram, good battery and mint condition screen. If i do buy the computer i would upgrade the ram to the max. What is the highest version of Mac os x that it will run? It is currently running 10.3. So what is the max you would pay?
