A eggbeater drill is as obsolete as it'll ever get. Good ones are worth hanging on to for those occasions when you need to drill a couple of holes some ways from the nearest outlet. Plus, kids love them and will happily spend a ridiculous amount of time drilling holes in scrap.

They also work in tighter spots than an electric drill. There's usually less bulk off the axis in at least one direction, generally opposite the crank. If you're in a corner, you're usually boned though.

The drills that are guaranteed to be trash in 20 years are the battery ones. I have a set and love them for when I need to drill more than a couple holes, but I have no illusions that I'll be passing them down to anybody because the batteries will be unavailable.
