I couldn't wrap my head around paying premium for what's basically the last gen processor. Pixel 8 will have Tensor 3. The Fold should have been priced accordingly. They used to purposely use the previous gen processors in the Nexus line to keep prices down.
I have a Surface Duo 1 and I really think they got the form factor right, as opposed to the folding glass one-big-screen types. The SD also folds backwards so you don't need (to pay for) three screens. Also, most of the functionality of the Pixel Fold is shown off as multitasking two apps side by side, which is exactly the power user use case the SD was made for.
IMO two-screen side-by-side folders could be down to $1K at this point if they didn't all employ fragile bending glass and superfluous outer displays.
Also, I like the idea of a Flip... again, without a big outer display. Give me e-ink on the outside or something for the clock and message previews -- I'll open the phone if I need to anyway.
Direct device-to-device connection, for one, though Matrix appears to be much more mature at this point.
