   My laptop which is 6 years old now has two rather slow cores.  I   
   bought it because I use it when I am "on move", that is I carry   
   it to places where I use it.  I wanted laptop with light, hence   
   small battery.  And compute power needs appropriate electric   
   power, faster/more cores would drain batteries faster.   
      
   I have rather new (I bought it year ago) mini-PC.  It has two cores,   
   significantly faster than my laptop but only two.  Again, its adantage   
   is low power use, I did not do exact measurements but its power use   
   should be comparable with newest Raspberry Pi.  It is fine as a low   
   end personal machine.   
      
   More generally, my impression is that 15 years ago there was limited   
   choice on x86 cores.  Now there are chips optimized for low power   
   and speed of CPU can vary quite a lot.  In desktop I have 12   
   fast cores (24 logical cores with hyperthreading).  Some people   
   here mentioned machines with mixture of fast and slow cores.   
   There are machines having a lot of slower cores.  And low end   
   machines like my laptor or mini-PC.  I did not met any new 1 core   
   x86 CPU in last several years, but 2 core ones are reasonably   
   popular.
