Use http://knockoutjs.com/documentation/plugins-mapping.html or https://github.com/Profiscience/knockout-contrib/tree/master/packages/utils.merge. The former is widely used and more powerful, the latter is orders of magnitude faster.

@IPWright83 Performance wise, deferred updates can yield dramatic improvements in some scenarios.

@caseyWebb Thanks - I can see your utils.merge
offering an example usage of updating an existing observable. I wasn't aware that it was even possible with the mapping
plugin which I've used a number of times in the past.
@brianmhunt yeah that's true, though in my case probably not an issue. That might be something to build into the mapping
plugin to offer a defer flag on it.
