According to a report from The Wall Street Journal, Dell is ready to readdress the luxury notebook market with a new ultra-thin offering to take on Apple’s MacBook Air. Dell launched its sleek Adamo line in March 2009 and its first model was an underpowered, over-designed offering that started at $2,000. Dell would later introduce less expensive Adamo laptops but consumers still wouldn’t bite, and the Adamo line was killed off in early 2011. On Tuesday, Dell will unveil its latest attempt to capture the hearts, minds and credit card numbers of prospective MacBook Air buyers with the slender XPS 15z. The new laptop will sport a price tag that starts at $999, and while Apple’s MacBook Air starts at $999 as well, that sum will only get you an 11-inch Air while Dell’s new notebook will apparently be the thinnest 15-inch laptop on the planet. Hit the break for a teaser video Dell ran earlier this month.
