Box.net Adopts HTML5  | read this item

Cloud storage and document sharing startup Box.net is the latest startup to adopt HTML5. The startup is announcing today that it is incorporating a broad implementation of HTML5 drag and drop functionality that supports native interaction with desktop. So basically, you can drag and drop files from the desktop right into your Box.net web application.

The feature works on Firefox 3.6 and Chrome for PC (with support for Safari and Chrome on all platforms coming in the next few weeks). Box’s CEO and co-founder Aaron Levie says that Flash didn’t allow this at all due to security issues. While this is a small addition in terms of functionality, he believes that HTML5 provides a much richer user experience when it comes to enterprise applications and the interaction between the browser and the operating system . “HTML5 is the nail on the coffin of desktop applications because we can create this rich interactive experience that acts like a native app.” Levie adds that HTML5 is also appealing because it works on every device.
