... no, don't believe misinformed Lenovo salespeople.
We have a USI 2.0 pen in the office: what you need to know [VIDEO]
With the Duet 3, we have a 2.0 in-cell display, and that is where things get fuzzy. For in-cell displays, the only option is USI 2.0, and that means this pen we now have in the office is the only option for those of you with the new Duet 3.
The Lenovo Chromebook Duet 3 just made your stylus obsolete
Whatever the case may be, if you're tempted to buy the Lenovo Chromebook Duet 3, just be mindful that you'll need to wait for USI 2.0 styli to become available should you frequently use one. We also have no clue if the first of those to arrive will be Lenovo's or a third-party model. At least an old-fashioned capacitive stylus will work if you're not one to touch your Chrome tablet with those oily sausage fingers.
.. so if you want to keep the Duet 3 & wait for a USI 2.0 to become available, I can recommend the capacitive $11.99 MEKO 2-in-1 3rd Gen Disc Universal Stylus Pen to use as a better finger in the meantime.
