HTML5…Good, but not perfect!
HTML 5.0 is a nice step towards higher web standards, but still not enough to get me going gaga over it. - There are some awesome examples of HTML5 integrating audio and visuals, but that's not what we really need.
Opera actually has taken a step in the right direction [with the navigation bar] allowing primary website links to be displayed in part of the browser, but not enough focus has went into this. I honestly think combining something such as OpenID into the browser itself could prove very useful.
I believe the browser itself does not provide enough basic functionality natively, by having the browser interpret and display components such as a top login bar could provide many benefits. This standardizes usage and could give the user a better experience overall.
