It also takes care of the fact that you might have a VT100 in one place and an ADM3 in the other; it presents a uniform virtual terminal to the applications, and maps it to your actual terminal. And, you don't have to explicitly detach. Screen will catch SIGHUP and detach your session. Great for flaky internet connections. And, if you forget to detach your session when you leave work, and only discover this when you get home, you can remotely detach and reattach it. Yup! Most of the better features of Multics, Tenex, TOPS-10, TOPS-20, and other OSes have been added to Unix. One could argue that the TOPS-20 command line parsing features that everyone seemed to like so much must not actually be too valuable, since no one has bothered to reimplement them (except Cisco).
