In iOS 6, you'll be able to compose new tweets and Facebook status updates with Siri--and both capabilities appear to be implemented smartly: If you link your friends' Twitter usernames to their Contacts entries, Siri automatically translates their real names as you dictate. That is, if I say, "Tweet 'Excellent dinner last night with Jason Snell, Dan Moren, and Serenity Caldwell,'" Siri will automatically composes a tweet like "Excellent dinner last night with @jsnell, @dmoren, and @settern."

On the new iPad, Siri can answer questions about weather and stocks, even though Apple hasn't (yet) ported its Weather and Stocks apps to the iPad. Apple did show a glimpse of a new default Clock app for the iPad, so we won't be shocked if Stocks and Weather finally make the leap to the big screen before iOS 6's official release, too.

If you have lots of apps, sometimes it's hard to figure out precisely which homescreen they're located on. In iOS 6, Spotlight makes that at least a easier, by listing the name of the folder a particular app is nestled inside when it appears in the search results.
