Another culprit pushing the PC refresh back, according to some system builders, is software. Marty Lantz, chief technical officer at MapleTronics, an Intel partner based in Goshen, Ind., said that in the past, new, powerful applications put pressure on hardware companies to keep pace and release faster components to run that software. But, that's not the case these days, he said. "The applications aren't pushing the hardware advancements as much as they used to, so you don't have the huge leaps between systems like you used to," Lantz said. While most productivity apps run by businesses don't require high-end hardware, there are other kinds of software that may need more powerful hardware, ranging from graphics-heavy applications to videoconferencing.
