Mobile application analytics

Just viewed this presentation from Google IO 2012, in which Google describe the new Google Analytics for mobile. The interesting part, is how they list what should be included in a mobile app analytics:

• User acquisition - Where should I spend my marketing dollars?

• Application store download - from which sources the download are coming (store search, web search, ad campaign, e-mails, referrals).
• New users
• Active users

• Engagement - Once the user get your application how they are using it?

• Engagement flow
• Top app screens
• Events
• App crashed - A bit overlapping with the app store.

• Outcome

• App sales
• In-app purchases
  
• Ad-monetization 
• Goal conversions
