This is a mount I designed to work with my macbook air 13inch and Lenovo 13inch laptop it can fit larger sizes you just have to move them farther apart. I used 2 of the medium velcro command strips on each of the mounts and 2 on the wall per mount (this is probably overkill but test at your own risk)

NEW!!!: I added new mounts that can hold a tablet and lap top together pictures coming soon. models now include screw holes for convenience
