This is the year of the convertible notebooks. Originally seen at CES 2013 earlier this year, the Yoga 11S is an 11-inch convertible Ultrabook. The system can be used in four different positions, hence the name Yoga. You've probably seen the ad for its big brother at least once; I've seen it probably hundreds of times.
Lenovo is offering quite a bit of freedom in terms of customization, with Core i3, i5, and i7 processors to choose from, either a 128GB or 256GB SSD, and 1366x768 or 1600x900 resolution screens. At its most basic configuration, the Yoga 11S will set you back around $800.
The device will start shipping in "more than four weeks" time making me believe it will likely utilize Intel's upcoming Haswell CPU's. You will, however, be able to check one out in person at Best Buy come June 23. It's available for pre-order at Best Buy and Lenovo.
