Developers
can often find answers to their questions through the Internet, but no one is
on the hook to research and respond to a embedded computer specific question. Open source
products are generalized in order to fit the widest array of users and can
force designers to modify the hardware configuration, resulting in higher
recurring cost for the embedded device. Cost
is obviously a major deciding factor when selecting an embedded operating system. Since there is essentially no cost of goods with software, vendors can
adjust their pricing model to generate revenue from various sources. Vendors
can charge for an initial license fee, development seats per engineer,
development tools, per-unit royalties, continuing support, or major upgrades.
To fairly compare prices, the overall cost of ownership must be computed for each
OS being considered.
