According to some friends of mine who still play AD&D and Battletech, not memorizing dozens of charts is for losers.Well, the 1E screen had the to-hit and saving throw tables. You needed a screen unless you wanted to keep flipping through the DMG constantly.
WotC D&D, thankfully, has gone with a unified resolution system, which gets rid of most of the real estate of the AD&D screens.
I still have fondness for that first amazing screen -- and would love it if WotC republished their 5E screen with the 1E art -- but I'd rather have a world where a screen is an optional purchase, rather than essentially a necessity.

P.S. Some people get offended if their system mastery is undermined.
