I'm a parent rep on a school ICT sub-committee that looked at ICT for the extension of our school that will extend into High School (grades 7-10, current school is only Kinder - 6) here in Australia. They were already heavily into Macs but we looked at equivalent Windows laptops and they came with no additional software and a heavy admin cost. For creativity the iLife software could not be beat. The iWork software was also dirt cheap for edu use. Then when it came to also using iPod Touch as handheld media devices for the students, any Windows solution was nowhere near for the price. Sure - you can get really cheap windows laptops but add on software and admin costs and there was no comparison.
