Their developers already knew Java, since most of their code was Java,
You're just trolling now. At this point, we both know that isn't true. Insisting otherwise won't change history.
Instead they locked themselves out of the biggest market in the smartphone world.
I don't even know how to respond to this. Android isn't a selling point. It's something informed buyers overlook, and the rest don't care about.
Being more or less absent from the market for several years was stupid
A good thing that never happened then!
You can predict the future! Amazing! How about this: What happens next year when BB has 128k screens and eleventy billion cores and users of last years Android phones see that; who's going to be envious?
To answer your question: No one. Because no one cares. All that matters to Passport users is "will this let me work more efficiently" It's an entirely different market than the market that you're in. You're in the market for a gameboy that sends text messages. A lot of smartphone users are as well.
The rest of us, well, we've got work to do. I mentioned earlier that my wife ditched her first and only Android phone for a BB. What I didn't tell you was that it wasn't the latest model, but an older one. It was slower and had a smaller display, but it was infinitely more useful to her. Managing her complex schedule and email was significantly easier and faster.
Different people have different needs. You want a toy. Passport and Classic users want a tool. You think BB should have abandoned their core market to sell silly playthings. They'd have been dead before the end of the quarter had they done something so foolish.
Go away now. I'm bored with your uninformed, ill-considered, ramblings.
