I have the Windows version and I really enjoy it. I would love it more if it had a better processor but hopefully Lenovo's next iteration is superior and runs on ARM. Sometimes it is a struggle to type using the Halo keyboard, but when I'm in a groove it's still faster than using the onscreen keys. I find that the biggest hurdle to typing isn't tactile feedback. The biggest hurdle is the size of the keyboard. It's small and thus typing can be a cramped experience (depending on the size of your hands, of course). I'm great at the keys near the middle but problems arise when I have to venture off to the sides. That said, typing on the Halo keyboard is a vastly superior experience than just using a onscreen keyboard.
Other than that, it's been a fantastic device. I don't use it to write as much as I used to (and I can't draw to save my life), but not having physical keys is immensely beneficial when using it purely as a tablet. Unlike usual 2-in-1s, I can hold the YB without the annoyance of physical keys ruining the experience. While I won't be typing out my thesis using the YB, I do a ton of forum posts and emails using it. I even installed
Lenovo's WriteIt app because it is simply better than the default handwriting software.
Given the price and processing power (or lack of it) I wouldn't recommend the YB as your only computer unless you were in dire need of a tablet with pen support. However, it's been a great little companion device to my various computers.
