Not to your face. hehe. Seriously, I basically have an open mind
policy. I'll listen to any idea, steal the good ones, and pretend they
are mine. just kidding.

You would be surprised how many people asked for A GTA02 -GSM
basically if you look at the costs of BT,WIFI,GPS, you are not talking
Big bucks. The big bucks are GSM, LCD, touch, processor.
BT, GPS,WIFI are peanuts.
I could prolly do tthe Gta02-GSM-Glamo for 199. sold direct of course.
And the markets you identified are exactly the kind of guys who came
at me. If you need telephony get a dongle..
