Bruce Lawson gave this talk at FOWA London 2009 (http://bit.ly/fowa-london-09).
The HTML 5 spec was originally called "Web Applications 1.0". Most of the attention has been on the new markup elements, but we'll look further at the applications side of the spec:
1. Dynamic images and graphs with canvas
2. Eliminating much forms validation with webforms 2.0
3. Local storage automagically saving your data
5. Building toolbars and menus.
