Mounting BGA parts (high density surface mount) for the hobbyist, and 
small businesses suddenly becomes easier/lower cost.

Previously, prices were at least 5x higher; this is going to have quite 
an impact on Hackaday projects etc.

... and of course the other manufacturers may have to follow suit.
