I gamed last weekend without a laptop. This was unusual, and I think the first time I've done so since coming to college. It started as kind of a lark, since I wanted to bring a thick notebook to scribble notes and maps and whatnot in and could not fit both the notebook, my laptop, and the ACKS Binder (a printed copy of the ACKS main rulebook) into my backpack. It definitely caused a few slight hangups, mostly in the transmission of henchman statistics (which we usually send via electronic means), but I think I liked it. It kept me more involved in the game, since I had no internet to distract me, and also removed any temptation to covertly communicate with my fellow players or look up errata or material from the Player's Companion (which I have not yet printed). Overall, it left me feeling refreshed after the game rather than tired, and sans the usual post-game headache to boot. Part of it might've just been unplugging at all really; it's fairly unusual for me to spend six consecutive waking hours completely without computer access. I should do it more often, and gaming is as good a time as any. As it is an escape from the real, so too might it be an escape from the machine.
I don't know if I could do it as a DM, though, especially for ACKS, where the ability to script automation tools is immensely useful for content generation. I guess I could generate content digitally and then print it out, but that extra step is kind of annoying, and has the irritating tendency to set things in stone / ink. Pencil is easy to edit, and digital is easy to edit, but when you start moving back and forth between them things get harder. But on the player-side, I cannot help but conclude that the no-laptop experience is more pleasant and generally better than on a laptop.
