I've not seen either of the latter two (yet).

Of the two laptops here,  I have one of each of those,  this Sony having the 
two-pin variant and the Dell I was using before that having the three-pin 
variant.  At one point I had the Dell with me but not the cord (and the 
battery on that one is unusable) and I had no difficulty in finding one to 
use.
