My school (newingtoncollege.nsw.edu.au) is entirely PC-based except for one iMac in the AV room and maybe a few Macs at a second primary school campus...they have decided to not use Macs after they switched to PC a few years back...I know that the out-of-date library computers are going to be updated next year...whats the possibility that they can be convinced to switch back by then? Is there is a possibility, can you make suggestions to how I can be as convincing as possible...
