Thanks for your post. After reading that, I probably won't be buying a 64 bit version of Windows 7. The only real advantage I see with a 64 bit OS is to address more than 3gb of RAM. For me, 2gb of RAM is plenty, even for virtualization. Having 2 identical dual channel 1gb memory modules is plenty for home use. It even works great with VMWare and 1 or 2 virtual clients. Heck, Ubuntu Linux runs great with only 1gb of memory and no swap file.
