Because it's a new OS, any distillation of a Windows 8 system has to include some observations about the inner workings of the operating system, particularly in regards to how it works with, enhances, or impairs the hardware side of the equation.
Because of its versatility, the Yoga is a great way to show off the powers and capabilities of Windows 8. It is essentially capable of taking on the profile of an All-in-One PC; you can just swivel the lower half of the device into stand mode, for easy listening or viewing.
In a similar manner, when you're on the couch in front of the TV, the tablet form-factor allows you to take advantage of the redesigned Internet Explorer browsing experience as well as quickly navigating between apps in the Metro UI (aforementioned touch inconsistencies notwithstanding).
However, this same versatility also accentuates a few of the operating system's flaws. The most obvious examples are the constant transitioning between the Metro shell and the Windows 8 desktop, or the inability to quickly access the Control Panel from the desktop. The lack of the Start button on the desktop really stands out here, as does the inability to quickly access the file manager.
At a deeper level, the Yoga's flexibility makes me want the ability to easily throw what's on it onto a bigger screen, like MacBooks and iPads can via Apple TV. Unfortunately, the OS isn't there yet, but it could be very soon.
We'll stop pining away because ultimately, Windows 8 makes the Yoga better, not worse. Once more apps starting coming through, it will function even better. Honestly, this device wouldn't even exist without it.
