Quick Tip: Go to a website via Universal Search

From the launcher or card view, type out the url you wish to go to, and hit the enter key (sometime you have to hit it twice). That will open up the browser app with the website you just typed out.

Universal search to include Twitter Search

In one of the series of Palm Pre emulator videos, It was revealed that Twitter Search will be supported in Universal Search. And chances are that even more would be supported down the pipeline (Ebay, Amazon, etc).

FYI, a Twitter App will also be waiting for you in the App Catalog at launch.
