Surely this is a feature
All this simplicity, however, is overshadowed by one missing key feature: push email. For most people, email is time sensitive. You need to know when an email hits your inbox so you can respond (or at least read it) right away. That’s why you need push notification and why Sparrow for iOS is disappointing in that regard.
This kind of thinking is why people work late, look at their phones when at shows/cinema/dinner/talks/anything they should be engaging with and it’s why relationships fail. How have we got to a point where an email is critical to life? Most of us aren’t saving lives or putting out real fires. If you think you ‘need’ email to arrive straight away and alert you immediately, have you ever really thought why that is?
