What should I get for my Android phone to help with the transition from an iPhone?

Alan is thinking of getting a Samsung Galaxy Note 2. He's planning on getting DoubleTwist and moving his Calendar and Contacts to Google. Is there anything else he needs to add? Leo says that there's also Locale, which is an equivalent to the Siri geo-fencing. It's $4.99. Leo also says that there's a todo list that works with Locale, called Astrid, that will work as well. There's nothing quite like the Siri integration on the iPhone, however.
