How can I convince my boss that I need more contemporary technology in order to do my job?

My boss hates technology. His answer to everything is, "Well, the way we always have done it before is..." He barely knows how to use his own computer. My work is in a very high tech area. I travel a lot, constantly have to attend meetings where everyone else has wireless laptops and often IMs or e-mails comments or doents to one another during the meetings. I am usually the only one there with a pen and pad of paper, and when they e-mail something around to everyone in order to discuss it, I'm sitting there saying, "Huh? What? I don't have that doent," and trying to look over somebody else's shoulder to view whatever they are talking about on somebody else's laptop. It is embarring, not to mention that it makes it hard to participate fully in the meeting. My boss also won't buy the software I need to keep track of my accounts (I am the contract administrator for our software and technology contracts). He tells me to use an excel spreadsheet, because "that's the way we've always done it in the past," but this is just not adequate in today's business environment. I am constantly worried that my lack of adequate software is going to cost us big bucks some day. I have told him all this, and his answer is always, "well, the way we always used to do it was...." How can I convince him that the contemporary business environment is different enough that "the way we always used to do it" isn't adequate any more?
