Keep in mind that the budgets from which High Schools operate are generally very tight. I was fortunate enought to attend a suburban school for which a levy had never been voted down. This meant that although we used Macs, they were almost always under 3 years old in the HS, and over this summer we (meaning those of us working as "summer tecnicans" [sic]) installed over 100 new computers, about 2/3 of which were G4-450 towers with half of those having 15-inch LCD monitors, the remainder were iMac DVs. I agree that boot time is terrible, but since most machines are required to run a wide variety of programs, the numerous "extentions" (just call them DLLs for crying out loud) that cause the slow boots are necessary. As for Bess, my HS used (and still uses) it as well. Bear in mind, however, that Bess or a similar program is required if the HS wishes to have the Government pay for the internet access, otherwise the money must come out of the operating budget. The high point of Bess was when I was researching a topic on world government for my Honors Government class and Bess prohibited access to the British Embassy's website, though I did E-mail the people at Bess and got the site unblocked. As for bandwidth, sort of a problem even though we had a T1, useage (sp?) was around 80% so it did slow down on a regular basis. Shared computers will always be less reliable than individual machines which can be taken care of properly. HS computers take quite a beating at the hands of the "computer illiterate", more often than not the cause of a HS computer's crash was attributable to something stupid done by the previous user.
