Oh, I forgot. I guess this is the new normal ...

How is Google making money out of Android?

I wait patiently until a genius is close enough and after that pretty much any pen will do.

I'll come to insult you more - after I go through these numbers and make sure they are correct.

I've made a simple stopwatch app for Symbian. I entered it into Nokias store when it opened I think 2008. Its sales have actually gone up instead of down even though there has been more competition than in the past. Of course it is the best one in mobile ;), but still I don't think that Symbian is quite dead yet. Besides Nokia is still making most of its smartphone money from Symbian.

You win some you lose some. Nobody can predict what kind of phones people buy two or tree years from now.

There is a lot of whitespace activity in Europe. Here is one summary.

I don't know if it is that straight forward. I wouldn't recommend open sourcing your first round of code if it is the core of your business, but then again you should have copyright to your own code and if you are clever enough it gives you street cred when you try to sell the stuff. Competition is usually busy trying to figure out their own problems and if they copy from you, you can use it in your marketing and perhaps in future lawsuits. It's pretty rare that you've actually invented something really new and if you have I guess patenting would be to way to protect that. If you want to drum up publicity I doubt going open source is going to do that in your prospective customers.

Of course not. Thought of killing people with swarming drones turns me off no matter how justified the cause.

but, somehow I wouldn't feel good when my code worked in this case

helped me, yet again, realize how little I understand quantum physics.
