The Ultrabook standard is a new standard that Intel is trying to introduce to the mobile computing world, but it looks like Apple’s MacBook Air is doing well enough for itself that it could be hindering the sales of Ultrabooks from other manufacturers. This is thanks to Q2 results which revealed that only 500,000 Ultrabooks were shipped, while 2.8 million MacBooks were sold, with a sizeable portion of those belonging to the MacBook Air. Addtionally, IDC analyst Jay Chou estimated that only 1 million Ultrabooks would be sold by the end of this year. While the notion of 1 million does seem like a big number for folks like you and I, it is only a fraction of his estimation of 225 million laptops which are to be sold by the end of the year. This is also way below the 40% marketshare that Intel had expected Ultrabooks to cover. Chou has also suggested that customers could be putting off their purchases as they wait for the release of Windows 8, which is expected to be made available later this year.
