I hope not. I see far too many business applications that waste I can't imagine how many person-hours on terrible mobile apps/sites. In some segments, the people who want to use your app on mobile just aren't the people that your business can add value to (not because of their choice of device, but because of what their choice of device indicates about how they plan to use and value your product). Don't spend your time ticking boxes of competitors' features. Specialize.
