First consumer available USI pen for newly coming out Chromebooks & tablets. Normal price is $ 70, so this is not bad. Lenovo will soon launch a AAAA battery powered USI pen for $ 40-50. Asus will launch a rechargeable for $ 60-70. This HP is a rechargeable. I prefer rechargeable, so this looks like the best price on one of those for the near future.

There are not too many USI models yet, but the technology has some big brand names behind it. Supposedly it will replace EMR. USI is the active technology that works with the Lenovo Duet, and it seems most Chromebooks will use USI moving forward.
