For devices that you keep at home any kind of batteries are really just a workaround for actual wireless electricity. Anyway my point is that most people that buy wireless trackpads probably already own power-sucking devices like digital cameras and so have invested, and are accustomed, to charging their batteries. In this case keeping additional non-rechargeable batteries wouldn't provide any benefits and would only add to confusion, as you have to be careful not to mix them. If you are not already enslaved to your digital camera's power inefficiency then perhaps buying brand new batteries might be more comfortable. In regard to environment your 24 pack of AAs wouldn't probably have any significant difference whatsoever and you won't live long enough to observe any. The impression, though, that rechargeable batteries are more environmental friendly will provide you with nice dopamine boost each time your device needs resupplying.
