How do you like to communicate?

I have a blackberry addiction. There. I've said it. I feel anxious when I can't find my phone or leave it behind, and the mere feel of the device in my hand gives me a sense of overwhelming comfort. As disturbing as my PDA dependence might be, I have noticed that I am certainly not alone. Most of my friends (who, like myself, are in their early 20s) also carry around their crackberrys, iphones, treos, etc as if the devices were little electronic lifelines. We use them to text message, blackberry message, surf the web, check our email, and, of course, to occasionally also make phone calls. The emphasis here is on 'occasionally' though, because we are a generation that tends to prefer the anonymity of emails and messaging over the personal nature of a phone call. I go to absurd lengths to avoid speaking on the phone (and I am actually fairly phone competent): I order food online, I buy my clothing from online stores, and I even communicate with my parents via email. Of course, my parents were quite averse to this means of keeping in touch at first, as they are both more than happy to actually hear the sound of another's voice, but I think they've come around.

So here is the question that I pose: how do you like to communicate? Do you prefer emailing to phone calls, or vice-versa? If a client contacts you by phone or email, do you respond using the same medium or will you respond to an email with a phone call or a phone call with an email? Do you use a PDA? If so, have you found it important to your business to be able to stay in touch at all times or does that accessibility cause aggravation?
