   Apparently, the "largest" NORs are in the 64MB range (512Mb).   
   Large enough for a sizeable bit of code without resorting   
   to dynamic application loading (which is somewhat wasteful   
   and potentially less reliable given most embedded CPU   
   capabilities)   
      
   SSDs seem to rely on fast interfaces to leverage the   
   larger capacities oF NAND without significant penalties.   
      
   And, the "removable" market assumes devices have short lifespans   
   (as their users likely discard and upgrade frequently).   
      
   So, for any *sizeable* application, dynamic loading seems   
   to be the only practical solution -- let NOR find a role in   
   just booting a system (SoC) and expect it to pull the   
   app(s) in, as needed.   
      
   [Of course, there's no guarantee that what you loaded   
   some hours/days/etc. ago is still "intact"...  hence the   
   folly of NAND]
