Lenovo has their 4GB and 8GB Duet 3 Chromebooks on sale right now. Their MSRP is normally more than $400 each. The 4GB model is on sale for $279 and the 8GB is $289. There are a limited supply of 8GB models at that price. I’ve been using the 4GB model all year and it performs web browsing, eReader, and media consumption well. I assume the 8GB is like the 4GB, but quicker. The 8GB also comes with a USI-2 pen.
