It's a very sturdy system, unlike those magnetic keyboard cover accessories that can't support the tablets they're connected to when placed on your lap or a less-than-solid surface. Overall, I'm grateful for the Yoga Book's touchscreen since I used that more often than the trackpad to navigate.Even with the Halo keyboard's shortcomings, I would use it more often than the keyboard on, thanks to the watchband hinge that connects it to the display.

If the trackpad had a little more room at the top, the Halo keyboard overall wouldn't be that bad to use on a regular basis-not at the regular speed or comfort level of a full laptop keyboard, but it's doable. It's also awkward to have to hold down the left-click key and tap the trackpad at the same time to bring up the options menu. I wish it had more space on the top because I often ran over it and hit the Space key instead of working within the trackpad's limits. It measures about 2.75 x 1.5-inches, not including the slit-like rectangles on its sides that act as the right- and left-click buttons, and it's simply too small to use properly. This is a magnetic board that fits over the keyboard and has dotted A5-sized paper in it. The keyboard also doubles as a Wacom digitizer, allowing you to use the Real Pen and the new Create Pad with it to draw and scribble on the screen.We'll get into the Create Pad technology in its own section below, but the Yoga Book also comes with an additional attachment called the Book Pad. There are no physical buttons or keys on it when you power up the Yoga Book, the backlight illuminates the outlines of traditional keys and the trackpad, almost like drawing lines in the sand with light.

It's more like a tablet that, instead of having a detachable keyboard or a folio case, has a slim slab attached to it. It is a convertible, however when I first unboxed the Yoga Book, its appearance struck me so much that it was hard to place it in the convertible category in my head.
