I am a freelancer who has a "work machine" & "home machine" in the same environment as well as a laptop. Home machine serves as a backup in case of a crash on the work machine. There are days I have no need to power up work machine. Having to log in or close out of all machines to use a third is really irritating since I'm paying $50 a month just to have the software in the first place. Recently, my Mom was in and out of the hospital & the laptop served as a critical savior in my work. There just needs to be a bit more wiggle room there. Thanks.
