My much used Oasis is getting long in the tooth and I’ve been looking to replace it. I was hoping to get away entirely from the Amazon ecosystem, but the fact is, the Oasis is, for me, both aesthetically and ergonomically perfect. Ironically, the only thing really wrong with it as an ereader is Amazon...
I’m thinking to just buy another one to future proof my e-reading habit. I’ve tried others - Kobo & Pocketbook - but don’t like them.
What I’m wondering is, have Amazon done anything sinister since I last updated the firmware, which would prevent me using a new Oasis the same way I use the old one, ie keeping it entirely offline and independent of Amazon (apart from initial compulsory registration of course) and buying my books from Kobo store & elsewhere and converting and loading via Calibre.
My 10th gen Oasis has firmware version 5.15.1, which works fine and minds its own business.
Does anyone here have an Oasis (or Paperwhite I suppose) with up to date firmware (5.16.21) and use it the way I do?
I’d try updating and testing, but if things do go amiss, there’s no way to reverse it of course.
