The Kindle is merely decent as an eReader, now that the Paperwhite is available and only for Amazon's proprietary format books. If one wants to do something fancier like reading PDFs or free-hand annotations it quickly becomes clear that the Kindle is just a vehicle for Amazon's book business and they developed it exactly as much as it was necessary for that purpose. Large format eReaders like Sony's DigitalPaper or the reMarkable show a glimpse of what's possible. There's no reason why such a device wouldn't be able to show and edit spreadsheets and also sync with some enterprise server or cloud. But there are few customers that would be interested in that. The eReader market is propped by the eBook ecosystems, it's not at all a market where the devices offer a competitive advantage. So... completely wrong analogy IMO.
