No, I have a pilot friend at THY, he is an Airbus pilot. He said me "We have to calculate aircraft's weight and have to arrange flaps for take on with some formulas, I was doing this by a book since iPhone, Now I easly calculate this without book. Also another app for record my flights. There are wonderful applications for pilots at iPhone". You know a lot of developers just develop their applications for iPhone. Some of them develop for Android too. A few developers develop for WM too... I noticed that, when this discussion begins you talk about fart apps... :)

>That's a bogus argument. A large percentage of iOS apps have never been downloaded. Another very large percentage do the same thing as other apps (how many fart apps do we need?)

>>Actually I tried WM8, it so fast and good OS I think. But it's too late. Windows store is so small, no one want write for WM8 because of small market, market can't grow because of no one write apps for WM8. Vicious circle.
