can you install on all your devices

There are no technical restrictions preventing you from installing it on all of your devices, however there are legal ones. The license "allows you to install and use the software for your personal, non-commercial use on all the Macs you own or control that are running Mac OS X Snow Leopard or Snow Leopard Server".

As for your work Mac, the license also allows "Commercial enterprises or educational institutions" to "install and use one copy of the software for use either a) by a single individual on each Mac Computer that the enterprise or educational institution owns or controls, or b) by multiple individuals on a single shared Mac Computer that the enterprise or educational institution owns or controls".
