Well, as promised, we are talking foldable this week. The excitement is palpable, and it looks like the rest of our mod team have already started the conversation here. Go check it out.
I honestly don't know very much about foldable phones, so I'll let the rest of our (very smart and knowledgeable) mod team handle this one this week. :)
Last thing for future reference at the end of the week, we also have a great thread discussing foldables here too, go check it out if you want more great discussions.
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.
