For the longest time, Samsung has been accused of being an Apple copycat. In fact, there was a years-long court case revolving exactly around that. It's not a one-way street, though, and there are definitely ways in which Samsung paved the road that Apple would later tread. Large screens and the S Pen immediately come to mind, with something like the iPad Pro combining both in the most extreme way. Unfortunately, Apple has since surpassed Samsung and the latter's newest Galaxy Tab S7+, while an impressive upgrade, still fails to regain its lost ground.
