Just read about this in my local paper:
A national campaign starts Sunday that aims to help people improve their balance sheets by encouraging them to save automatically. "America Saves" week, starting Monday through March 2nd, brings together more than 1,000 gov't agencies, corporations, and non-profit groups with goal of increasing consumer understanding of the need to save, whether for emergencies or to make the down payment on a home, to educate the kids, or to finance retirement. For more information, go to http://www.americasavesweek.org.

I can personally say that automatic savings is VERY easy to do - and I do not miss anything. DH and I have our 401K/457b deductions taken out of our checks. We also have automatic deposits to various mutual funds and savings accounts (one is ING Direct). The only thing I cannot do on auto-pilot is an IRA. We are usually on the cusp between a ROTH and a non-deductible IRA because DH's income can fluctuate somewhat. So we do not make those deposits under the following January.

I also checked out americasaves.org - it is a related site with more great information.
