Actually there are tons of applications for it, it's just that they're
all embedded applications so the typical home user would never see
them. And saying there are no applications for it "yet" is very
misleading as QNX has been around much, much longer than most current
operating systems. (According to my "UNIX Family Tree" diagram, the
first flavor of QNX came about in 1981, called QUNIX, and was released
in 1.0 form as QNX in 1984.)

QNX is not intended to run desktop workstations, it's intended to run
embedded devices. Although that's not to say you can't do stuff with
QNX, several of the "media terminal" type devices, like the iOpener and
I believe 3Com's "Audry" use QNX as their base OS. The reason is that
you can fit the OS, GUI, internet browser with plugins, email client and
a few other applets in 16MB of flash RAM because it's designed as such a
compact system since most embedded applications have very limited
RAM/storage space.
