Microsoft Windows Group Director Barry Goffe believes the driver issue is now "already less of a gating factor," but that "the real issue that's in front of us around broad usage of 64-bit comes back to the applications." Goffe points out that there are few mainstream 64-bit apps around right now, and that the small 64-bit installed base creates "a little bit of a chicken and egg kind of thing."
CNet contrasts the Windows world's 64-bit woes with Apple's next version of MacOS X, code-named "Leopard", which will reportedly support both 32-bit and 64-bit drivers. Mercury Research analyst Dean McCarron tells CNet, "Some applications require the extra performance delivered by 64-bit drivers, but most don't, at least not right away." However, Barry Goffe retorts that the number of devices Apple has to deal with is much smaller than Microsoft's. "The problem they are trying to solve is a much smaller problem," he asserts.
