The unique security and user friendliness of the Coinomi wallet is part of the puzzle when it comes to public acceptance of bitcoins and altcoins. New users are often unable to comfortably trade at typical currencies where numbers are bouncing around on both the buy and sell sides. But trading through Shapeshift makes the process extremely simple. Anyone, even advanced users, will likely see the benefits of using a Coinomi wallet.
The only concern about Coinomi is that it is no longer open source. However, there are many other great wallets that are not open source (eg Exodus and Jaxx).
