Kobo will soon let you upload and sync your own ebooks across devices, for a price

Kobo is launching a new monthly subscription service called Stack that lets users upload and sync their own ebooks and documents across multiple devices and apps, including reading progress, highlights, and annotations. The service costs $3.99 per month in Canada and £2.99 per month in the UK. Users can upload ebooks and documents from their local library, and the service is similar to Amazon's Send to Kindle feature but costs a few dollars each month. The initial rollout is limited to six countries, including Canada, Ireland, Australia, New Zealand, the UK, and Spain. The service is not available in the US. Kobo Stack's e-reader support is currently limited to recent devices, but access for older devices will arrive soon. Users have a 60-day grace period to download and back up any files they've uploaded and to export their notes and annotations before they are permanently deleted. Other features of the new Kobo firmware update include the ability to add multiple library cards to borrow books from several libraries through Libby.
