The Sentis Libra gives an iPad Pro a keyboard and trackpad, allowing it to act as both a tablet and a laptop — something no MacBook can do.

However, rival keyboard maker Brydge accuses Sentis of using its patented design. Cult of Mac has both a Libra prototype and the most recent Brydge Pro, and we compare the two and let everyone judge whether the accusations made against this device stand up.

The Libra is undoubtedly great, including a highly-functional trackpad. So the real question is, who deserves credit for the design?

Libra is redesigning its iPad Pro keyboard with touchpad to avoid a recent lawsuit from Brydge.

The keyboard’s creator, Sentis, has publicly apologized to Brydge. But after reviewing mockups of the Libra’s redesign, Brydge says the changes are not enough.
