I'm sorry you feel it that way. So, I can tell you I am very happy to have HP Prime on my android phone. Its capabilities are so far ahead from other competitors. But this doesn't mean HP Prime is perfect (for example COPY/PASTE as only method how to export/import things doesn't solve everything and it is really from stone era).
