I'm not going to go into the gory details of my job, but it involves tracking multiple conversations with a lot of different people both within the company and without.

Yes, I need a computer. Simply keeping on top of what I've said to whom and when would turn into a full-time job and I'd need my own secretary.

A single scheme update (the basic unit of my work) can involve conversations and data exchange between a couple of dozen people, in the extreme case.

And computers aren't crutches in MY corporate life - they're the tools with which we provide information to the driver at the roadside (and back again), 24 hours a day, 365 days a year - that's what we do.
