I am in a similar predicament. Yes its a bit frustrating. We've had a few brief talks about it and he is trying to curb it a bit, he might be receptive if you just bring it up in as an observation, and let him know you are concerned he might be missing out on other things. My bf isn't talking on the phone, he's searching, researching, forums, stocks, texting.. ect. He is also an IT tech, and I think he feels a little lost with constant information being fed to him through a screen. I think it's perfectly reasonable to ask for sometime with out the distraction.
