Okay, this goes way beyond a reasonable wish, into ha-ha-you-must-be-kidding territory, but …
Those of us in the UK and of a certain age harbour an unreasonable nostalgia for Psion’s PDAs, first the Series 3s and then the Psion Series 5 circa 1997 (https://en.wikipedia.org/wiki/Psion_Series_5). These were not today’s touchscreen machines, but actual pocket laptop computers optimized for typing on; at roughly 350-400 grams weight, when closed they were about the size of a modern phablet with booster battery. They were also the smallest machines ever to offer a real touch-typing experience.
The old keyboard-based PDAs vanished from the market around 1999, but not everyone has forgotten them. And there is now a new one in the offing, the Gemini PDA, currently on IndieGogo (it made its funding target), due out in November: https://www.indiegogo.com/projects/gemini-pda-android-linux-keyboard-mobile-device-phone.
The physical design is by the same people who designed the Psion 5 PDA. But the guts are all new: modern high definition touchscreen, bluetooth/Wifi/LTE/4G, 64Gb SSD, and a ten core ARM CPU. It’s intended to dual-boot Android and some flavour of Linux — probably Sailfish: https://en.wikipedia.org/wiki/Sailfish_OS. (Sailfish is a descendant of MeeGo, a collaboration between Intel and Nokia which leveraged Nokia’s work on MaeMo, which was their attempt at a linux-based replacement for Symbian — itself the ultimate evolved descendant of Psion’s EPOC/32, the OS the Psion 5 PDA ran.)
If the Gemini used an Intel processor and ran Windows 10, like the GPD Pocket and similar netbooks, getting Scrivener to run on it would be straightforward enough. And if it ran Android, the answer would be obvious, too (i.e. “nope”).
But this architecture … looks a bit like an edge case. (Clears throat.) I know that there’s been some success running Intel Windows executables on ARM/Linux using WINE, but I suspect there are a lot of gotchas lurking in the woodwork.
Anyway, it’s obviously not going to be a core commercial item of interest to Lit’n’Latte unless Planet Computers are wildly successful beyond anyone’s imaginings, and it may well not be possible at all unless the OS distribution they pick supports attempts at running Intel/Windows binaries under WINE. But I thought the idea of something in the form factor of the Psion 5 running Scrivener was just too good not to highlight.
