This is my newbie post to the Forum, so please excuse dropped clangers.
Way back, around the Dawn Of Humanity when IBM was marketing OS/2, their legal paperwork included text that could be reduced to: "We don't care how many machines you install a copy of OS/2 on, if only one is in use at any one time."
Is this still true of AOS? My hope is to use a desktop machine for work (mainly fiction writing with scraps of 'C' programming), keeping a notebook as emergency backup (once purged of Windows 10). If materials must be moved between them, I can use USB sticks, thereby keeping only one m/c in use at a time. Does this count as legal and ethical behaviour? Or must I invest in 2x AOS-5.1?
