Re: The best mobile OS in my view...
AmigaOS didn't even get a standard widget set until 1990 and never had protected memory. One therefore has to question the designation of 'best in class' when e.g. OS/2 supplied both in 1988.
Android, iOS and other handset OSes are designed so that the user never explicitly closes programs. That's why it isn't particularly intuitive on either of them — whether it's iOS's long press or Android's digging through the system settings. Thinking that you need to close programs is akin to a superstitious belief.
It is sad that people didn't want WebOS but it was pushed very heavily, with TV commercials featuring U2 and deliberate public spats with Apple (ending up in the USB Implementers Forum if memory serves) to get the bloggers on side. People simply didn't want it, because 'proper multitasking' actually isn't a feature they care about. The availability of Angry Birds, Temple Run, etc, is more interesting. Consumers are more interested in the total sum of what they can do with a device than with the technical way in which it is done.
