The main reason to keep nicads charged fully is that they have a high
rate of self discharge - if you just let them sit on a shelf they will
lose up to 25% of their capacity per month.  The reason to discharge
them fully then recharge them occasionally is to prevent the 'memory
effect'.  You don't have to worry about either of these with LI-ION
batteries, and about the only big difference is that LI-ION can only be
recharged about 1/2 as many times during their useful life.  (500-1000
times compared to 1500-2000)

>I'm somewhat familiar with what lead acid and NiCd's like, but what about lithium ion?  My laptop has a litium ion battery, and I'm wondering, should i recharge it once it's at a low percentage, or is it best to keep it at a high state whenever possible?  Should I periodically discharge it even when I don't really need it, or is it fine during periods of no use?  Does it have any special requirements at all?  I've seen very little information on lithium ion batteries on the net, I'm hoping someone in here knows a bit about the chemistry of the battery who can enlighten me.
