I'd be paranoid on the soft displays for now... but I really liked the Flip when the Samsung rep let me play with it as he was setting up the display. Like the Fold, it needs some work... really gotta make the outside screen take up the full front side when closed. The Flip was really cool. Surprised how close to a full size phone when opened. The Fold to me just too chunky for now. Going in right direction with larger outside screen.
If I was the kind of guy to have multiple phones or get new phones every year... I'd really think of playing with a Flip. Price was more reachable for me than the Fold and if the screen got all scratched up in a year, I'd move on lol.
The RAZR was cool because of it's nostalgic look and size/thickness looks right and outside screen decent... just low spec and the build not as solid as the Flip I hear??
The Apple Flip concept someone whipped up... Man if Samsung could easily do that design! The Flip I thought from pics looked too much like a pocket make-up mirror?? But in person looked good. Maybe go with matte/frosted finish and a darker color for my tastes lol. Maybe after I buy a phone this year and in a 2-3 more years I might be ready for a Flip/Fold. They do look like fun though.
