Indeed. Another advantage of this tablet over Remarkable is that it should be possible to set up synchronization with many more cloud services, including Nextcloud. Remarkable is limited to the biggest commercial cloud providers.

Furthermore, reMarkable doesn't actually sync anything. You can download files from the cloud but it's a one-way, user-initiated thing

I dunno, it seems to sync your notebooks back up to the cloud & other devices pretty well.

It’s £3/month after the first year, but it still syncs. https://remarkable.com/store/connect

Sorry, you're right in terms of their own cloud. I meant the syncing with Google Drive, Dropbox, etc, which is quite limited
