Good quote from the blog: "The truth is this: web standards are often a tyranny to developers and designers alike. By themselves, they constrain just as much as they free, and they are designed not for our benefit, but primarily for the benefit of platforms and software on which our solutions run."

Very true.

Kendo UI Mobile (beta)

http://kendoui.com/mobile

jQuery-based. Automatically adapts to native layout/styling conventions of iOS and Android.

Performance is one of the things we think we're doing really well with Kendo UI. We're jsPerfing everything we put in Kendo UI to make sure it's as fast as possible.

Ultimately, impact on page performance largely depends on how you use the tools (same goes for .NET). Used correctly, Kendo UI will help you deliver maximum perf for rich UI.

Hope that helps.

That's a fair point. jQuery, jQueryUI, and jQuery Mobile are all very much under the same roof.

The plug-ins are a different story. Some are more "official-ish" than others. So a developer using only jQueryUI must research, find, and add these to a project to "build out" a complete starting point.

We're trying to save developers that time, and provide an unified library that's simpler to learn, maintain, and upgrade. I think it's more than semantics, and when you compare performance, you should also see it's more than just features.

Hope that helps.

Disclaimer: I work for Telerik (who makes Kendo UI).

Kendo UI is a relatively new entry in the HTML/JS UI space, but the engineering is based on over a decade of building professional UI for the web. We are working hard to build a complete framework that has everything you need to build sites and mobile apps with HTML5 and JavaScript.

Some of our advantages: - Based on jQuery (familiar & less overhead for jQuery fans) - Built for performance (JSPerf us against anyone. We're fast.) - Clean, simple, easy to learn API - Lightweight and modular (use what you need) - Aggressive roadmap (3 major releases each year) - Affordably priced ($399 with a year of updates/support!)

We just shipped a beta of Kendo UI Mobile, and our next major release will happen in March. The best way to compare Kendo UI, though, is to download it and give it a try. It's fun to use and I think you'll enjoy the developer experience.
