A mobile operating system is an operating system for mobile phones, tablets, smartwatches, 2-in-1 PCs, smart speakers, or other mobile devices. While computers such as typical laptops are 'mobile', the operating systems used on them are generally not considered mobile ones, as they were originally designed for desktop computers that historically did not have or need specific mobile features. This distinction is becoming blurred in some newer operating systems that are hybrids made for both uses.
MeeGo is a discontinued Linux distribution hosted by the Linux Foundation, using source code from the operating systems Moblin and Maemo. Primarily targeted at mobile devices and information appliances in the consumer electronics market, MeeGo was designed to act as an operating system for hardware platforms such as netbooks, entry-level desktops, nettops, tablet computers, mobile computing and communications devices, in-vehicle infotainment devices, SmartTV / ConnectedTV, IPTV-boxes, smart phones, and other embedded systems.
The Nokia N9 is a smartphone developed by Nokia, running on the Linux-based MeeGo mobile operating system.

The Sailfish watch is a wearable devices that connects to a Sailfish smartphone and can display and control more functions than only time. It is not a production model, but a proof of concept study aiming to show that Jolla can bring Sailfish to many different shapes and form factors. The goal is to get it done on the watch and prove that the OS is well designed for smaller form factors and easy to navigate.
Accione is a low-cost hi-tech smartphone with Sailfish OS or Android from the Bolivian company Jala group developed in cooperation with Jolla.

The OS is open source Linux and have ability to serve additional closed source components from 3rd sides built-in the OS special layers for personalisation and marketing purposes by partner manufacturing a particular device. The real multitasking of Sailfish OS allows to run and use together many software applications, switching them in the fly in real time, without freezing them in background. Number of apps running together is not fixed by OS, but it is limited by amount of memory every next app requires to run and amount of free memory available at the device, until next app can't be launched.
The Youyota Tablet, 64bit device running Sailfish OS above 2.0 upon direct official license from Jolla, is successor and resurrected from oblivion incarnation of Jolla Tablet with the same original design and specifications, but 4500mA battery and versions with 32 or 64GB of built-in flash storage.
