I miss a working Yappari, but that has not caused me to start thinking about something else. N900 is more than a WhatsApp device to me.

Anyway, imho this talk about alternative OSes is OT in this thread. There's other subforums and threads for it.

(when my N900 dies, and when I cannot find another, I'll probably move to Tizen, Jolla, or Android, depending on my financial situation at the time)
