An example of Single task, single user Operating system is Palm OS for palm handheld computers.
Handheld operating systems are small devices that perform basic tasks such as email, web browsing and scheduling. Since the unit is much smaller than a traditional computer, it has a smaller memory, a slower processing system and a smaller display.
i would say it is due to the lack of processing power, memory and storage capabilties of the handheld system in comparison to that of a PC, the Operating system will be comparable to that of older PC operating systems developed for less powerful computers. Lots of people say that Linux is the best because it wont get so easily overloaded.
