Being a founder of a todo-list featured in the article (Todoist) I find your comment quite ignorant. Modern task managers aren't just about managing text. For example, our app integrates with Gmail, Outlook and Thunderbird and makes it easy to manage your emails. We can also send you reminders and you can access your tasks on 9 different platforms, including iPhone and Android. We can manage your links via our plugins for Chrome and Firefox. We also take care of sync so you can have your tasks, emails and links anywhere you go. We also try to visualize your productivity. We include very powerful calendar features (for example, you can write "every mon, fri at 8pm" and our date parser will understand it - - and you can even do this in 10 different languages and we will still understand it). Plus a thousands other things that your text-file solution simply can't do.
