Actually should be the other way round.  Doubling of word size means that every pointer, file reference, standard integer etc takes up 8 bytes instead of 4, thus 64bit apps almost always have a larger memory and disk footprint than equivalent 32bit app.

Maybe it doesn't need to access the pagefile because it can use all the RAM, vs the 32-bit which cuts the RAM storage in half?

Or I could just be entirely wrong. But it always seems my HDD drive starts spinning up a lot more in 32-bit than 64-bit

If you're using applications which do use a heapload of RAM, then that is a possibility.  Considering that most users don't, seems unlikely.

You need to make sure you're doing a fair comparison, ie both running on clean installs.

Do a comparison on RAM usage between Vista 32bit and 64bit - you'll see that 64bit uses around 50% more RAM.
