Fujitsu used to offer them --- their Stylistic ST-4110 was my favourite device for a very long while, used as for maps/navigation as well as an ebook reader in addition to being my main computer --- quite miss it and the simplicity of a single (stylus-equipped/daylight-viewable) device, as opposed to the ménagerie which I currently use (Samsung Galaxy Note 10+, Book 3 Pro 360, Kindle Scribe Coloursoft, Wacom One attached to MacBook)
