Thanks for the datasheet,  it complements the one I have from microchip.

The one bit of info I'm looking for,  though,  is what sort of limits there 
might be on the number of write cycles for those parts.  Is this one of those 
deals where there's a limited number of them and then you're screwed?

That limit would have a lot of effect on which applications one might want to 
use those parts in,  by comparison with other stuff.  I see lots of different 
possibilities for NVRAM of one sort or another,  ranging from EPROM 
replacement (probably a good one for EEPROM) to datalogging to all sorts of 
other stuff -- with each application having different numbers of write cycles 
one might expect to have available in the device.  I see an awful lot of 
people seeming to use flash devices as if you can just keep on writing to 
them indefinitely these days,  and I'm sure that's not the case,  though it 
may be that the number is so high it doesn't make all that much difference...
