Hi Leo,
       I remember many years ago not long after GSM came out, I
purchased a new phone and was going through the user manual and came
across this new feature called SMS.  I went back to the phone shop and
asked if it could be set up because I thought it was a good idea.  The
reply...    Nobody would use that!

I believe that if it becomes fully operational across all networks, as
SMS is now, then it could easily take off.  Sure most users would
probably be young people as with SMS, but I know many older people that
are involved in radio are very interested in it also as we may be spread
over a large distance or not handy to a radio at the time.

It could be a nice alternative to vision impaired people who cannot make
use of SMS.  I also see it useful for small businesses who need to keep
contact within their own group rather than having to make numerous phone
calls, great alternative to having two-way radios and more secure!

There is potential for this but until all networks have it and it is
cross-network capable it is next to useless, let's face it SMS didn't
really take off until it was capable of going across all networks.
