Hi everyone! I was just wondering: Bought a SP 2 256 some weeks ago and needed it to be replaced by microsoft. Just received my shipping notification of the replacement unit (advanced exchange) and realized that the unit that is on the way has a serial number that resembles the one of the old unit. It is not the exact same number, more like (these are just example numbers): Original: 032.......12345 Replacement: 007.......12345 So, the last 5 digits of my new unit are the same - that cannot be a coincidence. Thats why i was wondering if microsoft is building new "individual" replacement units? Since the serial number of the surface pro is "lasered" into the unit, it has to be either this - or microsoft has some serial free refurbished units laying around, waiting to be "serialized"? Also the first digits are lower (2 zeros) than the original unit (1 zero) Has anyone noticed this with their replacement unit? I am just curious Cheers markus ps: i am located in germany - so pls excuse my typos and lack of correct grammar.
