This is to offset the larger memory footprint 64 bit programs have (because of 64 bit instructions that is 8 bytes vs 4 bytes for 32 bit programs).

There is an increase in memory footprint, but like said before definitely not double. If you have 4 or more gigs of RAM it's worth it IMO, but more is better of course. A processor that works in quad words is rapidly becoming standard, if you have the memory it's silly limiting yourself to 4 bytes a register and a maximum of 2-3 GB of data in memory. Reading data from a hard drive into memory is super expensive performance wise.
