If you are using a phone, it's just an interface for one or more computers somewhere. So, sorry old school guys, you're technically using a computer if you use any phone nowadays. Now, you might be able to construct a valid argument with ham radio. I'd like to see some hard head get by with a ham radio and no use of any phone or any computer.

My current job is impossible to do without a computer. Also, any dream job of mine requires a computer. The killer is what somebody said above about the Tax Man requiring a computer. That really ends any argument right there. Either you need to know how to use a computer, or you must pay somebody who knows.
