      Issues
      Current version in market (Windows Mobile 6) lacks support for some popular technology enablers (e.g., multi-touch, GPS, accelerometer)
      Next-gen version will be late to market
      Less developer enthusiasm vs. that for iPhone and Android
      Application distribution more difficult today vs. iPhone’s app store

      Apps viewed as competitive to Apple are often shut down
      Downloads highly dependent on “featured” or “top download” promotion in store
      App store is the only authorized distribution channel
      Apple / hardware dependent
