      • 13. Power-user devices
        • Internet tablets: N800, N810
        • 14. “ Mobile computers”: N900
      • Why Maemo?
        • Easy to develop for
        • 15. Afterwards: port to other platforms
      • Qt through package (shipped by default)
    • 16. MeeGo
      • Merge of Maemo and Moblin

      • 22. Smartphones (mid- and high-end)
        • Symbian^1: Series 60
        • 23. Symbian^3
      • Not Series 40 (“mobile phones”)
      • 24. Qt through package (easy to install)
      • 25. Many devices: UI reimplementation (easy)
    • 26. Desktop
      • Possible (libirail)
