In fairness, iFixit does point out that Surface devices get more repairable with each generation, plus I'd point out that many flagship smartphones of 2020 are equally as hard to get into. But still, such lack of repairability is worth noting. As usual with video embeds, click through and maximise quality and resolution for best results.
The wiring loom through the hinges was especially interesting - my experience of bending and twisting wires in folding designs has been mixed over the years. But in this case it looks like the batteries that will be the weak link, starting to degrade and swell a couple of years into the device's life in catastrophic, non-repairable fashion. But hey, anyone rich enough to buy the $1400 USA-only Duo in year one will almost certainly have traded it in after 12 months for the Duo 2 in 2021, so at least batteries won't be their problem!
