Great stylus to match if you've picked up the Lenovo Ideapad Duet Chromebook from the recent sales.
RRP of $59, but only $39.83 delivered at their education store (you'll need an education account, .edu.au address usually needed for signup).
The Lenovo USI Pen is great for extended notetaking and writing, fine art or graphic design. The pen with its USI protocol supports Chrome OS and provides an industry-leading 4096 levels of pressure sensitivity for natural writing and sketching, along with a 150 days battery life based on 2 hours in active use daily.

(For other systems, just check whether it's USI compatible or not.)
Works well with the Duet!
Anyone else find these are draining much, much faster? Lenovo refuses to accept it as a problem.
FYI, while AAAA batteries are expensive and can be hard to find, you can use the cells from most 9V batteries (as used in smoke alarms).
These are labelled "6LR61" , ie 6 x LR61 cells, which fit the Lenovo pens.
Note that the polarity may be the opposite of what you expect: the outer part is the positive anode, so put them in "backwards".
Metal-case batteries like Duracell are easier to open, as you can gently pull open the metal at the seam, rather than cutting a plastic shell.
