MobileTechWorld notes the sessions cover the Trail API, which will help increase conversion from lookers into buyers 2-3 times. Loke also mentions at the end that only PG13 and lower apps will be allowed (around 36min30sec), which unfortunately is pretty consistent with Microsoftâ€™s family friendly policies.
He also notes the Marketplace will use real money, via credit cards, not Xbox points, but operator billing will also be supported. Apparently the upper limit for app purchases is $499, and free apps are discouraged by offering only 5 for $99, and $19.99 for each subsequent one. An unlimited number of paid app submissions are included in the $99 yearly subscription.
At around 36 min Loke notes that if developers breach the criteria for marketplace Microsoft can revoke their license, which will result in the application being uninstalled from all Windows Phone 7 devices carrying it.
At around 50 min, Loke notes only a maximum of 20 MB will be allowed to be installed over 3G, although a lot more can be downloaded via WIFI or USB. Earlier he mentioned application updates will be OTA, but due to size ROM updates will only be available via USB and the Zune software.
The live demo on an actual device starts around 11 minutes.
