Of course it is - but it still remains that in a competitive environment, passing costs on to the customer is not desireable. Therefore, anything that can reduce costs is considered necessary.

While it may not result in development costs, it is likely that it results in support costs. Customers will complain about performance, and even if the answer is to upgrade - it still costs support time and effort.

And this is part of the point I have made over and over - there is no such thing as a free lunch. No matter how good it is, it creates costs for someone to deal with. That doesn't mean you don't do it, but to sweep it all under the rug and say it doesn't exist is... *marketing*.

Nonetheless, the original point was (and is) that the average user does not need it, and therefore has little incentive to move to it. As you indicated, even those who *do* need it may resist.

I am still waiting for a convincing argument that in 3-4 years the percentage of those using a 64-bit system will be so high that 32-bit systems will be a very significant minority (say, 30% or less of installed systems).

Based upon your own experience, how 'current' are most of your customers machines? In my own office, at least half of the staff still use PIII based systems, and 99% of the rest use P4's.

Regards,
Dean
