This dissertation comprises three esssays that study the decisions of system innovators in mobile computing to "open" development of their systems to outside suppliers and the implications of doing so. The first essay considers this issue from the perspective of which components are retained under the control of the original innovator to act as a "platform" in the system.

    Die Geschichte PSIONs 15 1 Einführung Anhand der Entwicklung vom kleinen Softwarehaus zum größten Computerher- steller Großbritanniens, kann man die Innovationskraft des Unternehmens PSI- ON und speziell seines Gründers zeigen. Der vollständige Überblick über die Baureihen führt bis zu den aktuellsten Geräten, die teilweise noch im Ankündi- gungsstadium sind. 1.1 Die Geschichte PSIONs Die Firmengeschichte PSIONs begann bereits vor zwanzig Jahren – da noch ohne die bekannten handlichen Taschencomputer. Und wie so oft benötigte es eines charismatischen Menschentyps, der seine Visionen um jeden Preis reali- sieren wollte. Hier war es ein Universitätsprofessor mit einigen ausgewählten Studenten (oder soll man sagen Anhängern?), die den Sprung ins Unternehmer- tum wagten. 1.1.1 Der Gründer Dr. David Potter, groß, schlank, 57 Jahre, ist Gründer und Vorsitzender der PSION Plc. Nach Eigendefinition einerseits Rebell und andererseits Akade- miker aus Leidenschaft, der eine Professur am Imperial College London in Ma- thematical Physics innehatte. Nach Jahren der Lehre (auch an der University of California) unternahm er alles, um Geld für eine Firmengründung aufzutreiben. Mit einem Startkapital von 100.000 Pfund gründete er 1980 in der Londoner Baker Street die Firma PSION, die bereits 1984 den Organizer erfand. Ein wei- terer Geniestreich war wohl die Erkenntnis, das Betriebssystem EPOC zur Basis des Gemeinschaftsunternehmens Symbian zu machen, das nicht nur alle wesent- lichen Handyhersteller vereinigt, sondern sogar dem Microsoft-Imperium am PDA-Markt ernsthafte Konkurrenz bieten konnte. David Potter und seine Fami- lie halten zur Zeit ca. 19% der Aktien eines Unternehmens mit circa 1 Milliarde Pfund Börsenkapitalisierung. 1.1.2 Der Name „PSION“ Bereits den Firmennamen PSION umranken viele Legenden.

Processing III.b. Memory Management III.c. I/O : Input/Output IV Features V Strengths VI Weakness VII Example of Applications where the OS is being used VIII Screenshots I Introduction More than 90% of the CPUs in the world are not in desktops and notebooks. They are in embedded systems like cell phones, PDAs, digital cameras, camcorders, game machines, iPods, MP3 players, CD players, DVD recorders, wireless routers, TV sets, GPS receivers, laser printers, cars, and many more consumer products. Most of these use modern 32-bit and 64-bit chips, and nearly all of them run a full-blown operating system. Taking a close look at one operating system popular in the embedded systems world: Symbian OS, Symbian OS is an operating system that runs on mobile ‘‘smartphone’’ platforms from several different manufacturers. Smartphones are so named because they run fully-featured operating systems and utilize the features of desktop computers. Symbian OS is designed so that it can be the basis of a wide variety of smartphones from several different manufacturers. It was carefully designed specifically to run on smartphone platforms: general-purpose computers with limited CPU, memory and storage capacity, focused on communication. Our discussion of Symbian OS will start with its history. We will then provide an overview of the system to give an idea of how it is designed and what uses the designers intended for it.

It's manufactured in 1997 and made in the UK. It was very popular for business men because of the stable OS, named EPOC. (Now known as Symbian OS) It's powered by two AA batteries. It has a 640x240 pixel greyscale LCD with a backlight. The keyboard is generally considered to be amongst the best for its size, with large-travel keys and touch-type capability. The most common problem was a design fault in the screen and keyboard cable. By opening and closing, the cables get stressed and lead to vertical lines on the screen.
