   Other PC manufacturers are following suit on this one - especially in   
   Ultrabook models where the quest is to maximize battery life while slimming   
   down the thickness and weight of the case.   
      
   Eliminating the battery compartment door mechanism frees up space that can be   
   used either for a larger battery or a smaller/thinner case (or a bit of   
   both)... it creates inconveniences down the road when the battery fails, but   
   manufacturers hope that users will replace their laptop by then anyway.   
      
   So while Apple did it first, they're (as is often case) finding lots of eager   
   followers.
