From the Wikipedia article on lithium ion batteries:
A disadvantage of lithium-ion cells lies in their relatively poor cycle life: upon every (re)charge, deposits form inside the electrolyte that inhibit lithium ion transport, resulting in the capacity of the cell to diminish. ... At a 100% charge level, a typical Li-ion laptop battery that is full most of the time at 25 °C or 77 °F will irreversibly lose approximately 20% capacity per year.
I don't know whether the capacity loss would be as bad for an e-reader battery as it is for a laptop battery - probably not. However, I still think it is something to consider. I once bought my sister a Rocket Ebook which I don't think she ever used. Now its battery is dead and will not take a charge. I'd rather not have my e-reader turn into a brick like that.
Where did you see the 1,000 charge statistic?
