Hi My daughters primary school has Apple PCs in each classroom. They have recently purchased 2 new PCs (also Apple) for the library. The guy who installed them commented that they were too good for the library, and would be better off in classroom where the kids would get the benefit of their superior memory. The school Principal has been told that she would have to take the older PCs into town, as only certain places are authorised to purchase/install Apple memory. Is this correct? - having had no dealings with Apple whatsoever, Can you just buy Ram for them the same as other PCs, and is it just as easy to install?, or are they completely different inside?
