Key points from his unboxing:

• Questions: is this form factor really a good idea?
• VERY satisfying hinge that snaps closed delightfully
• Less of a folding crease in the display than the Galazy Z Fold
• When it's open: perfectly 1-handable
• You can definitely feel the ridges and bumps
• MKBHD could NOT open the phone with one hand

Some things it DOESN'T have:

• No wireless charging
• No SIM Card
• No expandable storage
• No dust or water resistance

One awesome thing it DOES have (that only works with folds):

• Snap the phone closed to end a phone call

His main point seems to conclude the following:

• The fold seems like a good idea if it allows you to put something larger (like a tablet) in your pocket, but he would rather just get a smaller smartphone than the RAZR.
