I can see why GPS based apps, or camera apps with filters, or networking apps 'need' to be installed apps (I don't know if an easy way to do GPS through a browser; speed and fast access to storage) ... but Amazon, Reddit, newspapers, ... what am I gaining?
Genuine question as a one time web dev I've always considered web sites written as an app, shipped with a browser, to be a negative. What am I missing out on?
