The laptop I need for my job (Windows) has a fine old time telling me  
I need to plug in a power source soon or I'll lose my work. However,  
it always tells me this *after* it's just gone to sleep due to low  
battery. I find it wonderful guessing how much longer I have before I  
need to plug in.

You'd think so, wouldn't you? So did Steve Jobs...
Apple laptops only have one "sleep" mode, and you just described it.  
This doesn't apply to any of the PPC models or some of the early Intels.

Not really. How hard could it be? I mean, all you'd need would be  
some kind of monitoring device capable of extrapolating data -- now  
if only there were some device on board which already did some data  
processing, you could re-use that...
