For me, the best way to think of Mana is to compare the experience with that of custom painting your car Pink.
It will no longer really matter what car it actually is, all people will notice is that it's now pink. It's a pink car, not a Seat. Any car painted pink will lose it's identity to a certain extent, but geez will it stand out from the crowd.
Now if you happen to really like pink, you will now own the finest set of wheels on the road.
And of course you might benefit from therapy.
PS. Didn't Natalie Cole do a song in the Nineties called "Pink Mana Rack"
