Quote from the whitepaper:
They provide a perfect user-experience similar to native applications, irrespective of device type and operating system.
Perfect user experience with the platform or with all the apps in the platform? If all the apps available in the platform can give perfect user experience then this platform is amazing.
It says similar to native apps, so the performance that it would give us would be comparable to native apps that we are using today that are offline but can be used across any device and operating system.
