Thanks for all the commentary -- it gives me a pretty neat perspective. I had supposed that 2E was where minis play had declined - but to see quite a few of the 1E players who never played with minis (or to be more accurate, spatial representation) is surprising to me.
For my part, my old 1E group played with Risk pieces back when they were plastic roman numeral I's, III's, and V's, and we used the V's for the PCs, and the I's and III's for monsters - so we always used "minis" in some fashion. In 2E, we fell away from that, resumed minis in late 2E (1998 or so) with real lead and pewter minis, and then when 3E came out used minis from there on out. Oddly, though, my first D&D experience was without minis - I trained on the Moldvay Basic Game, and we didn't know what minis were, back then...
For 1E, I felt some of the nuance was lost when minis play wasn't used -- for instance, burning your allies with fireballs or lightning bolts, or getting whacked by the orc with the spear when you charged him without wasting a turn to carefully engage him.
Oh, and

Weird, laser guided bomb accuracy for fireballs is guaranteed in most every edition.
Try telling that to someone in a Goblin warren or Ankheg burrow.

Using Fireballs as written in 1E and 2E is one of the most fun memories from my early gaming days, both as a DM and a player.
