This is a web browser with W3 tools built-in. It's nothing you can't do without Chrome/Firefox + Metamask (or Coinbase's future Metamask competitor). I do think it's a good idea, because you can reduce friction and polish the UI by integrating everything, but in the long run, if crypto is successful, I really think Firefox and Chrome will just adopt all these W3 technologies natively. It will be hard to compete.

Brave already comes preinstalled with MetaMask. Still, I think there will always be demand for third party key management like Elph provides.
