People and Machines: Some students may have physical difficulties that are addressed by their laptops. If they aren't able to use their laptops then it is harder for them to use any IT systems at school.
Globalization: By using their own computers, students have easier access to communication. For example, if a student is working on a project and they need to contact an outside source, it is a lot easier to just their own laptops then for them to have to go and jump through all the hoops that school computers require.
Control: Students have more control over their work when they use their own laptops. If they have to use the school computers then there are always problems with file compatibility and the transferring of information that the student needs. If the students have use of their own laptops, they can rely on their technology more.
