It would be great if we could add a computer so we could have three devices licensed. With most of us using a desktop workstation, a laptop, and now a portable tablet, three devices seems better than two.
You can install on three different devices but only two can be active at a time. Many people in this situation today, have the software installed and activate and deactivate as necessary. Do you use all three devices in the course of a single day?
Okay, that is a good idea. I do not use them all on the same day and the tablet is only a "once in a while" need for Lightroom and Photoshop. I am going to try this and see how easy it is to deactivate and then activate.
