We have seval of the mobile carts in either PC or MAC. They come 15 to a
cart and have a hub for internet. I've used them twice. It works well with
a small class. We have to have each kid sign in and out the computer. The
last time, 2 wouldn't work. I liked it better when I could sign up and go to
a lab with one computer for each student. These are more cost effective.
