Having to install a completely separate version (64 bit) of Windows at a higher price, and then shop around for replacements for all the apps, while having the OS at the same time, look and act exactly the same is a big problem. The average user sees no reason to "switch" to 64 bit anything and will not jump through any hoops to do so. This is also part of the reason why Microsoft's 64 bit strategy, (which is actually ahead of Apple's in terms of most implementation details), is such a colossal failure. So when they go to install an application, they have no clue what version to use. If you take an average consumer, they wouldn't know if they're running a 32-bit version, 64-bit version or whatever.
