With Samsung poised to reveal its latest take(s) on the smartphone in a matter of hours, we thought it was as good a time as any to take a look back. The Galaxy Note 5 and Galaxy S6 Edge+ are rumored to be on tap for tomorrow's festivities, two devices that would continue the company's affinity for super-sized phones and curved displays -- both of which are trends it started years ago. Of course, Samsung has experimented with a number of unique design flourishes. Some of them ended up setting the tone for the entire industry. Others, well, never really achieved liftoff (and with good reason).
