It's like tinkering with your car's engine--course this is from the days when you could see your engine and actually do physical stuff to it, instead of just changing chips in it's comp--you do it cause you can and it's fun. And in the process you get to crunch wu's faster, or manipulate data faster, OR have bragging rights ( like when you messed around with your car ).
Congrats on unlocking that XP, I was unable to unlock mine, just been too lazy to take it apart and try again Go for the gold, dude!
