# None are major contributors.
#
# Why contribute?
# - paid to do so (or business model, Red Hat, SUSE)
# - support their hardware (Intel, IBM, TI, Microsoft, etc.)
# - they rely on Linux, so they contribute to ensure that it doesn't change in ways that would not benefit them (Nokia, Oracle, Google.)

<b>Where is the roadmap?</b></span>
# everyone wants a roadmap, they are wrong
-- [images/ols_2006_keynote_08.jpg]
# We make changes when they are needed, based on what people implement, not what marketing dreams up would be nice for the next version.
#
# We take the changes when they are done, and work.
#
# We support more devices, and more processors than any other operating system.
#
# We do stuff no operating system ever has.
#
# The only one to work on a different major platform from what it originally was designed, we scaled up and down (embedded and supercomputers.) No one has ever done that.
