"The idea with this touch NTP is to focus (for now) on apps, and make it easy
to arrange them into pages. You can swipe/drag to switch pages, and press
and hold to lift an app and rearrange it," explains Google.
I found an interesting comment in one of Google's JavaScript files: "Note that, while the product portion of the touch NTP is designed to work just in the latest version of Chrome, this hack attempts to add some support for working in older browsers to enable testing and demonstration on existing tablet platforms. In particular, this code has been tested to work on Mobile Safari in iOS 4.2. The goal is that the need to support any other browser should not leak out of this file - and so we will hack global JS objects as necessary here to present the illusion of running on the latest version of Chrome."
