Rich vs. Reach


Go native development when you need rich apps and go HTML5 development when you need reach! HTML5 is the new kid on the block and is the perfect solution when you need to target the most number of mobile platforms.

You can target iOS, Android, WP7, WebOS, and Blackberry.

So how is HTML5 different from HTML? HTML5 is the latest version of HTML and XHTML. It attempts to solve issues found in previous iterations of HTML and addresses the needs of Web Applications.
