In order to look ahead, you need to look back.

Or at least that’s what we told four executives at the Mobile World Congress Americas conference in San Francisco this week!

We asked multiple innovators — from Ability Wearables’ CEO Shiv Madan to Samsung’s Eric McCarty — to share the number one thing they wish their mobile device still had. Some options included a physical keyboard, push to talk and even the game Brick Breaker (which you can still download, by the way).

Watch the video above to get some of the top responses at Mobile World Congress Americas.
