IGN has some nice photos of a never-released pad with a trackball instead of one analog - they say the precision was awesome and that it worked perfectly.I think that would be the case - that or cybernetic thumbs...
ORIGINAL: dasher232 I manage to keep the controller sweat-less but when people come over to use it I really get annoyed because I have to clean off their dirt from my controller which ain' t easy unless I take it apart.
