64 bit architectures are all about being able to deal with incredibly large numbers. In principle a 64-bit OS should be capable of dealing with and running earlier (8, 16, and 32 bit) software but backward compatibility isn't as simple as that and it will take a while for programmers to write programs that can take advantage of a 64bit system so those installing a 64bit operating system wont have many benefits for some time. It will also take time for hardware makers to provide (if they do so at all) new drivers for these OSes.

On the hardware side, 64bit CPUs wont provide many advantages without software that can fully utilise the benefits of handling more bits per cpu cycle and of being able to support massive quantities of memory.


PS Found a second article that may help with insight.
