Bookmarks management usually becomes a nightmare, especially if you use different devices or/and browsers. Modern browsers offer bookmarks synchronization, but if you use lots of computers or different devices it's hard to have your bookmarks available in a snap. In case you use different browsers for different tasks, it's impossible to have a common and well organized bookmark list.
With Cloud Drive you can have all your bookmarks centralized and accessible from anywhere, any device, any time. Isn't it awesome?
