On a 4 GB system you lose 600+ MB of memory when using a 32-bit

You can run 32 bit programs on a 64 bit operating system. The point
isn't that 64 bits is useless in general, it is just that most
*applications* work just fine as 32 bit binaries.
I can't believe the 64-bit processes are twice as large. Typically the
binary size is only a fraction of the amount of data processed by the
application. Moreover, most of the memory allocations contain array like
structures for storing bitmaps, I/O buffers etc. For example, if you're
storing 8-bit pixels in a game, you're not forced to use int64 data type
on a 64-bit architecture.
It all depends on what the largest payload is. One of my apps' largest
structures was a hash, which was almost twice as large in the 64-bit
version.
