yes to verify, for Home & Student it is 3 computers *at one time*. (you can
later 'de-license' any or all of the 3, and reassign to a different computer.
for home and office, it doesn't matter whether the additional computers are
desktops or laptops.
BUT -- if you have the OEM version of home and student, i.e. it was
preinstalled on the computer, you are more limited, i.e. usually limited to
that one machine ever.
(on other retail versions of office you are limited to 2 installatins at one
time, 1 destkop and 1 laptop, or 2 laptops *at one time*).
