Actually, at least in switching power supplies, ceramic capacitors are
now a good option. You can get ceramics of several hundred
microfarad, and they are quite small. More expensive than tantalum, I
expect, but more reliable. And if they do fail, they normally fail
open, not shorted as electrolytics do.
