Цитата: Standalone unit sales of Vista at U.S. retail stores were down 59.7 percent compared with Windows XP, during each product's first six months on store shelves, according to NPD Group. In terms of revenue, sales are also down, but the drop has been less steep, at 41.5 percent. The findings largely mirror the sales pattern NPD saw for Vista during its first week on the market in January.
