So I'll throw the cat amongst the pigeons by saying: Who cares about PTT?

Seriously - Push to talk - Half duplex Communications. How ancient is 
that! It's really reminiscent of ancient US style truckers - Smokey and 
the Bandit and all that. That's just so last century. Lets put all that 
behind us and get with the 21st century! We all have hands-free, full 
duplex communications now, so lets just forget all that old rubbish and 
get on with the programe.

I think a provider tried it over here for a while - Orange IIRC, but they 
charged an arm and a leg for it, so no-one used it. Everyone I talked to 
about it just laughed. If I want to talk to someone with my mobile while 
working, I use a bluetooth headset. I touch my "borg implant", say "HOME" 
into it and it dials home... I'm not going to hold an E90 to my ear, push 
a button, say "Hello? Can you hear me? Kchchchct" let the button go then 
wait for a reply.

I wish the mobile manufacturers would put as much effort into creating a 
DECT interface in their handsets as waste silicon space & time on PTT 
garbage.

If I really want PTT, then I'll go out & buy a pair of Motorola handsets.

Next thing you'll be asking for is flip phones with a little stubby 
antennae on top.... Thankfully they went out of fashion in the UK about 5 
years back.
