Kobo Launches Stack, a Monthly Plan for Syncing Your Own E-Books

Kobo is launching Stack, a monthly subscription for uploading your own e-book files (EPUB or PDF) up to 200MB. It keeps your place, highlights and notes in sync across Kobo's apps, website and supported e-readers. The first rollout covers Canada, Ireland, Australia, New Zealand, the UK and Spain, but not the US. A 90-day free trial is offered.
