With so many Windows 8 PCs launching in the next couple months, manufacturers are going to have find something to make their machines stand out. Lenovo has taken this idea to extremes with one of its new computers, the IdeaPad Yoga 13. Convertibles are nothing new – we’ve seen plenty of laptops that can “turn into” tablets – but the IdeaPad Yoga 13 features a 360 degree hinge that makes it so much more than just a tablet/laptop convertible. I’ll say this right off the bat: the IdeaPad Yoga 13 is one of the coolest machines I’ve ever seen. But being cool is only one part of the equation, and that 360-degree hinge can’t carry the whole machine if the rest of it is nothing to write home about. Has Lenovo delivered an interesting and unique machine that won’t disappoint when it comes to actual usability, or is the Yoga 13 a dud that will be lost in a sea of Windows 8 machines despite the fact that it has some intriguing features? Read on to find out.
