Most people - but there are plenty that don't or times when people don't. On planes for example (there are that have it but many that don't.) Do a search for "offline trello desktop" or look in the comment at https://blog.trello.com/trello-mobile-offline https://blog.trello.com/trello-mobile-offline. But I don't understand once you've solve the offline storage and syncing problems for one platform(sync/conflict resolution strategy), why it's so difficult on other platforms. Thanks for the link - but I didn't see how it's anything like trello. I need something like kanban, but not specifically a kanban tool (trello is general is how you can use it - it doesn't have to be limited to workflows)
