   Apple does something similar with recent Mac computers, making it   
   difficult to impossible to replace the factory installed SSD drives.   
   The claim has been that it is more secure (i.e. a thief can't steal you   
   computer, quickly replace the drive, and then sell the computer to   
   someone else). More recently some companies have been   
   reverse-engineering it to provide SSD replacement kits, which of course   
   voids any warranty.
