Benjamin Kerensa at OMG! Ubuntu! reviewed the System76 Lemur Ultra Laptop. He said, "Scrolling using the touchpad was effortless and with the two finger vertical and horizontal scrolling working in applications like GIMP became easy with an added layer of precision." and wrapped it up with positivity "After thoroughly testing up the System76 Lemur Ultra in it clear this notebook has high end performance, average look and feel and a excellent price model. One thing I loved about the notebook was that all of the hardware worked flawlessly out of the box which is not something I can say exists in all notebooks even those certified to work with Ubuntu by Canonical."
