I just need to say that I'm getting tired of people who argue against 64 bit. We should not need to defend 64 bit because of it's memory advantanges...
64 bit computing is not a hype, it the natural evolution of computing and will woon surpass 32 bit as the standard, if it hasn't already done so.
In the end, it's not about if your music will imrpove with 64 bit or that you need more ram for music, it's simply that 64 bit is the future, and for those buying new computers, it just doesn't make sense to buy a 32 bit OS at this point.
During my research for a new PC laptop, I noticed that 90% of computers now ship with 64 bit OS. If you really want 32 bit, you can still get it but I would guess for not too much longer.
The analogie I can think of is when touch-tone telephones were replaing the rotary phones. Sure you could stay with the rotary phone, it did everything you needed, but why would you? Eventually the technology of the touch-tone provided caller-ID and other tools that were impossible to have with the rotary phone. To me, those who argue for 32 bit are those who argue for the rotary technology and are living in the dark.
In a few years almost all computers will be running 64 bit.
