"That cute Linux penguin is looking to hide out in your next
embedded-systems project. What will it cost to let Linux in? Maybe
more than you think, so don't jump ship if you're already using
reliable alternatives, like VxWorks or QNX. Those might actually be
cheaper in the long run."
"Linux's lure is threefold. It isn't burdened by licensing fees,
source code is readily available, and there's a large choice of
free applications. All of this is true in general. But, the details
of Linux can bring about several concerns. ... Some Linux
distributions and products have licensing fees that even exceed
costs on other platforms."
"The cost of using Linux is a combination of determining its
suitability, and also having programmers and designers that are
adequately trained. Because it's new, Linux's costs can be large in
terms of time and money. On the other hand, these are often
one-time, up-front costs that can be spread across multiple
projects. These costs shouldn't be ignored, or be applied to
the first embedded Linux project."
