For the average home user, you are correct... 64-bit doesn't really provide any advantage. For gamers and video or photo editors, however, 64-bit is starting to make a lot of sense. 4GB of address space is starting to be a bottleneck for some... though not yet the vast majority. Does that mean we should continue to stall progress simply because most people do not NEED it right now?
The only way to push vendors to support 64-bit is to get the hardware and the OS out there. Vista x64 is precisely the reason 64-bit support has gotten as good as it is right now. With Windows 7, that support will continue to grow. Old hardware and software are bound to be left behind. I know it's nice to have a 10 year-old printer or scanner that still works perfectly... unfortunately, like everything computer-related, it eventually has to be replaced. You can sit an whine about it or you can accept it and move on.
Nothing lasts forever.
