[gui-talk] Windows CE, Symbain Wide Open to Attack

[Joel Deutsch]

Hi.   I don't own or use any devices of this sort, so I've never felt myself 
in any danger in that way.  But what you say sounds very logical, and it's 
reassuring to hear.
to know
Thanks.

It's important to keep in mind that, unlike many PC's, devices running 
embedded operating systems are highly unlikely to be compromised by rouge 
software.  It's much harder to get such software onto such machines, and 
there is little incentive for people to create such programs.

There is no practical threat here and little to worry about.

Thanks for the thorough rundown, but unfortunately, I don't understand very
much of the explanation for lack of background.  I'm asking this question as
an ordinary end user of computers and computer-related products, and wonder
if you could give me a couple of examples of products everyone's familiar
with that are run by an OS of this sort.  Some well known, popular PDA, for
instance?  Some kinds of cell phones?  Also, what is Symbain?  I never heard
that word before.

thank you.

Windows CE (sometimes abbreviated WinCE) is a variation of Microsoft's
Windows operating system for minimalistic computers and embedded systems.
Windows CE is a distinctly different kernel, rather than a "trimmed down"
version of desktop Windows. It is supported on Intel x86 and compatibles,
MIPS, ARM, and Hitachi SuperH processors

Windows CE is optimized for devices that have minimal storage - a Windows CE
kernel may run in under a megabyte of memory. Devices are often configured
without disk storage, and may be configured as a "closed" system that does
not allow for end user extension (for instance, it can be burned into ROM).
Windows CE conforms to the definition of a real-time operating system, with
a deterministic interrupt latency. It supports 256 priority levels and uses
priority inheritance for dealing with priority inversion. The fundamental
unit of execution is the thread. This helps to simplify the interface and
improve execution time.

Microsoft has stated that the "CE" is not an intentional initialism, but
many people believe CE stands for "Consumer Electronics" or "Compact
Edition"; users often disparagingly called it "Wince." Microsoft says it
implies a number of Windows CE design precepts, including "Compact,
Connectable, Compatible, Companion, and Efficient."[1] The first version,
known during development under the codename "Pegasus", featured a
Windows-like GUI and a number of Microsoft's popular applications, all
trimmed down for smaller storage, memory, and speed of the palmtops of the
day.
