The team at Chrome Unboxed did a deep dive into this (our sample didn't come with a pen) so if you're interested in the Duet 3 for doodling on it's worth checking out. It only seems to support Lenovo's own USI 2.0 digital pen, there hasn't been any kind of backward compatibility with the panel. The display also supports a digital pen but with a caveat. The kickstand can be adjusted with precision though so you can at least get it at the best angle to mitigate ambient light interference. As with most touch displays though it's really glossy and while it is bright enough to use outdoors on a sunny day, you're still going to see more of your own face. It's a shade under 16:9, but media fills it nicely and the 2K resolution means text is sharp and everything generally looks lovely. The bezels trimming it are nice and slim for folks who are into that, and while 5:3 isn't the most common aspect ratio, it doesn't feel strange. The display is a hair under 11-inches, but not far enough that we can't refer to it as that.

You can only use Lenovo's USI 2.0 pen right now with the Duet 3.
