Dell had long stuck by its direct sales model. Consumers had become the main drivers of PC sales in recent years, yet there had a decline in consumers purchasing PCs through the Web or on the phone, as increasing numbers were visiting consumer electronics retail stores to try out the devices first. Dell's rivals in the PC industry, HP, Gateway and Acer, had a long retail presence and so were well poised to take advantage of the consumer shift. The lack of a retail presence stymied Dell's attempts to offer consumer electronics such as flat-panel TVs and MP3 players. Dell responded by experimenting with mall kiosks, plus quasi-retail stores in Texas and New York.
