Since my evening job is printing RPG maps (see sig below) - of course I use printed battlemaps and one of our players has tons of figs, so battlemaps and miniatures all the way. As discussed on RP's poll - I don't use grids on them though, at least the maps I game with.

Since I print maps, it would be stupid not to have printed maps for gaming. I agree with Rav's statement - computer at the gaming table, no thanks!

I have seen a game using a projector screen, it was interesting and worked as a game, but I won't invest that much into a game - table, people, dice, map, figs and character sheets, and books for rules lawyering, that's all I need!
