I agree. 64-bit apps will only really be useful for developers writing software for a specific firm who have decided to upgrade all their PC's to 64-bit. It's going to take a few years before more than 50% of PC's out there are 64-bit, so in the meantime you would have to provide both 32-bit and 64-bit compiles of your app, or just stick with 32 bit which runs fine on both platforms.
I know of a high profile Windows 16-bit cashbook app that is still for sale and selling strongly after 15 years. Now that Microsoft decided to stop support for 16 bit apps in it's 64-bit O/S, they will have to move on to 32 bit.

I mean - the market for applications that specifically need 64 bits is really, really narrow. And the 64 bit Windows is really far from what it should be. On the other hand, considering Vista's hunger for memory, 64 bit Windows will be used more and more, by more people, and that will create more traction for it. I'm personally using Vista 64 bit so I can have +4Gb RAM in my host system, so I can run a +2Gb XP 32Bit Virtual Machine - and it's a pain, drivers are pour quality (if they exist at all). And I learned the hard way that "supports all Windows versions, including Vista" never means "Includes Vista/XP 64 bit support". I consider proper Unicode support in the VCL and generics to be much more important features! For me, 64 bit goes into the same category as dot NET: good technology to be used at some distant point in time. Just my 2 cents, Cosmin Prund _______________________________________________ Delphi mailing list -> Delphi@elists.org http://www.elists.org/mailman/listinfo/delphi
