   Lousy.   
   I think you mean micromachined, not nanotech.   
   The cheapest units read around 2G or so, with an error of some .1m/s^2 or   
   so.   
   Not very good.   
      
   Space applications are many things, for some things this level of   
   precision is totally fine.   
   For inertial navigation, for over a few seconds, it tends to be a problem.
