Query: Where did Dell miss out on sales due to relying on the internet?
Context: As a result, the company was selling a greater proportion of inexpensive PCs than before, which eroded profit margins. The laptop segment had become the fastest-growing of the PC market, but Dell produced low-cost notebooks in China like other PC manufacturers which eliminated Dell's manufacturing cost advantages, plus Dell's reliance on Internet sales meant that it missed out on growing notebook sales in big box stores. CNET has suggested that Dell was getting trapped in the increasing commoditization of high volume low margin computers, which prevented it from offering more exciting devices that consumers demanded.
