Well, depends what you mean by "deep"; I was thinking perhaps down to 30%; anything below that is just plain scary, as well as perhaps harmful... I thought that was okay, though obviously pointless.
Remember: LiIons are a completely different beastie than NiCads; the latter really craves the deep discharges.
Yes, which is why a flashlight is a valuable accessory for NiCds; I will not run any battery very deep in devices when avoidable, so I periodically throw a random pair of (semi-used, waiting for recharge) batteries in a flashlight, turn it on, and put my solar-powered watch in front of it to recharge overnight. In the morning, batteries are cleansed, and watch is full. (And atomic synced, since I do it on a windowsill.)
