Hello everybody. it is time to move from the PC world to Mac world and my idea is to buy a 24' iMac with the 2,8 Ghz CPU. Is the right time to buy an iMac or is it better to wait for new models? I know that is impossible to know when the new iMac will be announced but before making my order I would like to receive your advice. thanks a lot. Luca P.S. sorry for my bad english!!
