I saw his question as &#x27;why would I want an iPhone only service&#x27;, so that&#x27;s what I answered.<p>Venmo may have great market share <i>among people using apps to pay friends</i>. I&#x27;m suggesting the total pool of people is MUCH bigger and Apple could take a good chunk of those people, not unlike when the smartphone, tablet, MP3 player, or digital music store markets got MUCH bigger. Will they take it all? No. Probably not even &#x27;most&#x27;. But there is still a large opportunity there.<p>I&#x27;ve never used Venmo, but I wonder if they&#x27;ll survive or end up a player that was there too soon or at the start but is overtaken by the 2nd wave.<p>There are plenty of companies&#x2F;brands that fit that model. Diamond Rio, Palm, ICQ, Blackberry...<p>Or maybe the banks will come in and crush this market somehow. I know many are trying (BoA, Chase, USAA), but they may not get the UX to work well or be willing to cooperate between banks.
