Its promising, unfortunately search bar only allows for google searches, and settings doesn't help much with customizations, you can't have to-do list and calendar without the news feed (i suppose you can fix it by linking a dead rss feed, that way it'll show nothing), also you cant link any of these to an existing account (re, sync your own to-do's or calendars). Also you can't delete links to websites(amazon, aliexpres etc)
I think its a nice idea, and it might work for you if you usea this kind of things.
