your right I think.
at the same time, by making the SMA's opposite of the typical commercial HT, 
they have insured that the amateur accessory market for antennas thrives.
Not all commercial HT's are opposite of the ham gear though...a local ham 
who also operates his own small business UHF repeater, has several Icom 
commercial HT's that have the same configuration as the icom ham HT's and so 
on.
these are older, or at least, a few years older, HT's though and most are 
the same model, which I can't remember off the top of my head.
Great little HT's though...small, great audio and excellent user 
configurations for things like TOT, tones, squelch, display, alert tones and 
so on.

anyway, with companies like Wouxun and others designing their HT's more 
towards the commercial side, I think the big three and their supporting 
accessory manufacturers will begin to see some proffit losses in the next 
few years.
unless they start making accessories for the chinese radios as well, which I 
suspect they will before long...since wouxun at least seems to be taking off 
in north america right now.
I know of at least 10 local hams who have the dual band udp2? radio.
once you bore a hole in front of the microphone element, and remove the 
rubber membrane, the tx audio is extremely good...if you leave it stock, the 
tx audio is very low and sometimes difficult to hear.
