Not Just RRSP's

I just read from this post that it is more advantageous to put new capital into a non-registered account, than it is to put it into a registered account (ie. my RRSP).
I've always suspected that new investment money should go into a non-registered account, but I have been brainwashed by the mutual fund propaganda and big bank propaganda to make RRSP investing a priority.
Unfortunately, much of my retirement money is inside RRSP's. Still, it is good to know this hidden and obscure fact that the banks will never tell you about - they want you to throw everything into an RRSP, so that they can sell you more of their mutual funds. I think this will help to provide some structure and direction for my retirement investments.
