I'd add one more *big* advantage of linux: not too many people have
even heard of QNX, while a lot of developers are familiar with at
least one of real Unix flavors. When it comes to CE, it's still
relatively new, so there are not too many experienced people there
either.
Few developers --> unreasonably high costs + poor quality.
Oh yeah, one more, there is way more software for linux than for any
of those two.
