"There is not native support for exchange I don't think but it works so seamlessly that it almost doesn't matter. re: cloud storage: This is an issue across multiple services so it depends (crappy answer I know) In my case its Facebook and Gmail storing the data so therein is the trust. If they go down, we go down. Not sure about computer sync. Native media - video recorded looks good and plays back well. Having background tasks running is a big bonus - but also a big battery drain."
