Our school has somewhere around 720 computers. Starting this year, the school district has banned the purchase of any Macs or Mac technologies. This has raised much controversy with many people, as you can imagine. With the recent switch to DHCP which requires OS 7.6 or higher, they are running slower than ever. On top of that, things are starting to wear out such as power supplies in some 6100s and PRAM batteries.
Students break floppy drives, keyboards, and mice regularly.
With this new policy, none of these can be fixed or replaced. And, so slowly but surely, the Macs are being replaced with new PCs. Remember that these people think that the only Macs that exist are the ones we have at school. Macs are used some places and for some things. They think that Apple is still going out of business and the whole world uses PCs for everything.
