Dropbox

http://www.dropbox.com

Samples and Ideas

Students can install dropbox to their home computer, drag files to the icon, and then login online at school to retrieve their files, but they should NOT install dropbox on a public or shared computer. Instead, they should go to the dropbox website, login, and access their files. Otherwise, other students using that computer could access their files.
Educators can install the dropbox on their home and work computers and easily drag and drop files they want to access & work on at their various locations.

While students may want to install dropbox on their home computers, they should not install it on school computers since other students can access their files.
