Canonical wants to integrate services like WhatsApp & Dropbox into Ubuntu Touch.
Ubuntu Touch is Ubuntu for mobile devices, like smartphones and tablets. Instead of home screens you have “scopes” that mix together, for example, online sources of video such as YouTube with the videos saved on your mobile. The main idea behind this is you don’t need to open separate apps; if you want to watch a video, they’re all stored in one place. Essentially these are HTML5 Web apps and “scopes” are intended to be simpler to develop than a full-blown app.
According to a Dutch Ubuntu insider “Canonical talks with big services like Whatsapp, Dropbox to help integrate these services within the system rather than with dedicated apps. This reduces the porting costs in bringing these services to UT.”
Altough Ubuntu want to integrate Dropbox, OwnCloud becomes Ubuntu’s default backup service. There is no precise time frame in place, but probably these services will be available later this year.
