The original Lenovo Chromebook Duet was an interesting device. I bought one, and I loved it. The portable tablet-based form factor paired with an OS designed for laptop use was a big draw. As was being able to use the few Android apps I actually wanted to use on a tablet. The hardware was excellent, the display was really nice and the keyboard, while small, was good to type on. It had only one problem: It was really slow. ChromeOS performs well enough on basic hardware, but the MediaTek CPU inside the Duet just wasn’t really up to snuff.
