I couldn't agree more. If vendors decided to give the web development the resources it deserves, the experience would turn out vastly superior for the users: no apps to download (browser is usually bundled), well standardized consistent interface where you know what a control does and how does it look like, more control on security and safety, and a lot less resources consumption. Unfortunately heavy advertising, catchy effects, colorful interfaces, and not caring for the web side, convinced most users that the apps approach is the best one, while it's actually the other way around. Apps also give vendors a tool to more easily infiltrate users devices and grab much of their personal data so I guess the motivation to change that is less than nil.
