I don't want o feed trolls like ZogG but...

It just marketing talk. So far no company has shown any device with SFOS. I am sorry to say it but I doubt we will see it in reality.

SFOS still missing features that almost all devices has support for today such as bluetooth profiles(RFCOM?), usb host mode etc... and QT API to use internal/external sensors, bluetooth etc.

Some of that could be there if they upgraded Qt... Jolla say they are a SW company but they lack time to upgrade the most important core components? Now that makes me wonder how they can compete with Android? If they want that they must support this basic stuff.

You may now say: "such stuff is only used by geeks". Seriously no!

More and more people use they phone/tablet to connect external stuff as sensors etc. Turn on/off light in home etc... Connected via BT, serial etc...

And ofcourse geeks also use phone/tablet to connect to RPI, Arduino, STM32 Nucleo etc... Connecting sensors to Tablet, Phone is already mainstream. That's why we need more ready API.

The thing is programmers are lazy and not interesting to use low end hack to get basic stuff working.

It is a really shame every time I see a youtube clip where they use some Android device to connect to a sensor or STM32 Nucleo, Arduino etc... I often think: "Hey that I should do with my Jolla Phone" then I realise: "I need that X API, lets see if Qt has this. I should forget this I need Qt 5.4 making that work " or "I need USB Hostmode"
