My experience with 1e is as follows.
Low levels - The wizard blows his small pool of spells, then proceeds to play on his Game Boy, since he has no chance of being effective in any other regard.
High levels - The fighter and thief play on their Game Boys while the wizard mops up whatever challenge is presented.
In order to avoid these problems, I've found DMs have had to spend more time doing game design than adventure/world/setting design. So, they bought a game they had to fix before they could play it in a way that made it fun for everyone involved.
