As Intel failed to achieve its goal of having ultrabooks account for 40% of total notebook shipments with its Ivy Bridge platform, and the proportion only reached about 10%, sources from notebook players believe the goal may be achievable with the upcoming Haswell platform, which is set to launch at the end of second-quarter, 2013.

The sources pointed out that compared to Ivy Bridge, Haswell's stronger performance and cheaper price, plus the expectation that Windows 8 should become more standardized by then, should mean ultrabooks have a chance to account for 40% of total notebook shipments by the end of 2013.

Although vendors have released ultra-like notebooks with prices around US$699-899 as alternatives, since these devices lack attractiveness in terms of design and weight, while ultrabook models with specifications similar to the MacBook Air have prices a lot higher than the MacBook Air, most consumers have turned to purchase Apple's product instead, the sources noted.
