Loss leaders—products sold without a profit to generate interest—sometimes work. Acer tried it with its recent S3 ultrabook, but it isn't content with that; it has it sights set on cutting prices even further.
"The company is merely breaking even when selling its entry-level ultrabook model and the venture is only made worthwhile by the higher-specced SKUs pulling in a surplus."
While that doesn't sound like a sustainable strategy, Acer is actually planning to slash its prices even further. Their president, Jianren Weng, has been quoted as saying that Acer will push out ultrabooks as prices as low as $499 (converts to £350, but we'd likely see it at around £500 here in the UK) in 2013 to compete directly against Apple's iPad.
Not that we should complain: cost-price laptops aren't to be sniffed at. [The Verge]
