Thank you all for warm response! Honestly, Ubi is just an "hobby" experiment. I am not a professional developer and in fact I do not have a plans to be one. I tried to compare the Android vs QT development and for me, QT is definitely a winner. I am in love how intuitive and powerful all QT ecosystem is. I did Maemo, N9 and Symbian compilation without a single line of code change.. and almost in the same way I can release Ubi package for BlackBerry 10! It is amazing, QT is amazing!
