Scott, the Commercially Available CMU Wearable was referenced in the post you replied too! It was a long post ;-) The reason why I did not post the link is because its a PDF file and locks up the machine for a few minutes I don't want people clicking on that during a trading day.
Message 13272384 is the full text and I can not find link handy now anyway
Below is the text which refers to commercially available.
I was able to find a picture of the pre-production device on a page form 3 years ago.
here is the TIA-P within the CMU site

3.1 TIA-P
TIA-P is a commercially available system,
developed by CMU, incorporating a 133 MHz 586
processor, 32MB DRAM, 2 GB IDE Disk, full-duplex
sound chip, and spread spectrum radio (2Mbps, 2.4 GHz)
in a ruggedized, hand-held, pen-based system designed
state, the memory architecture is speculated to move 66
MB per second. to support speech translation applications. TIA-P is shown in Figure 4. TIA-P supports the Multilingual
Interview System.
Speech translation for one language (Croatian)
requires a total of 60MB disk space. The speech
recognition requires an additional 20-30 MB of disk
space.
Dragon loads into memory and stays memory
resident. The translation uses uncompressed ~20 KB of
.WAV files per phrase. There are two channels of output:
the first plays in English, and second in Croatian. A
stereo signal can be split and one channel directed to an
earphone, and the second to a speaker. This is done in
hardware attached to the external speaker. An Andrea
noise-canceling microphone is used with an on-off
switch.
TIA-P has been tested with the Dragon speech
translation system in several foreign countries: Bosnia
(Figure 5), Korea, and Guantanamo Bay, Cuba. TIA-P
has also been used in human intelligence data collection
and experimentation with the use of electronic
maintenance manuals for F-16 maintenance.
Operational Experience
The following lessons were learned during the
TIA-P field tests: wires should be kept to a minimum;
handheld display was convenient for checking the
translated text; standard external electrical power should
be available for use internationally; battery lifetime
should be extended; ruggedness is important. All these
lessons were used as an input into the design of the
optimized version, TIA-0.
3.2 TIA-0
The main design goals for the TIA-0 computer
were shrinking the size, reducing the weight, and
incorporating the lessons learned from the TIA-P field
tests. TIA-0, shown in Figure 6, is a smaller form factor
system using the electronics of TIA-P. The entire system
including batteries weighs less than three pounds and
can be mission - configurable for sparse and no
communications infrastructures. A spread-spectrum
radio and small electronic disk drive provide
communications and storage in the case of sparse
communications infrastructure whereas a large disk drive
provides self-contained stand-alone operation when there
is no communication infrastructure. A full duplex sound
chip supports speech recognition. TIA-0 is equivalent to
a Pentium workstation in a softball sized packaging. The Fig. 5 U.S. Soldier in Balkans Using TIA-P
