Microcap & Penny Stocks : Patriot Scientific - PTSC -- Ignore unavailable to you. Want to Upgrade?

Benedict (or anyone) - I'm trying to understand some of the
cost tradeoffs in a company adopting a new chip, using a
"homegrown" operating system (I forget the official name
for this), or using a 3rd party supplied operating system.

Maintainance and upgrade costs should are also being considered.

What I'm not sure of is the costs of bringing in and maintaining
a new chip. I know circumstances may be unique, but I'm under the
impression that adopting & maintaining the new chip will cost
less than the operating system (OS) costs. The primary reason for
this is that the OS will have many more changes over time than
the chip (or the development facilities associated with the chip).

For the different OSs, what I've seen is that there is usually
some point where it becomes more costly to support a "homegrown"
OS than going with a 3rd party version (assuming that there is
a need to stay current with the 3rd party's "new features").

Licensing costs for the OS can also impact the decision, e.g.,
a vendor plans to have 2-3 billion appliances in the field (of
course these will have the Patriot chip in them) and is faced
with paying to license the OS.

... this doesn't cover all issues, but I would appreciate
any thoughts on the hardware costs ...

Thanks,

Pilgrim
