>Upgrading is an investment in both time and funds, both can be spent better if you are already able to do what you want to do.

You are operating under the assumption that the usual way of dealing with technology is that you have some goal, and then you search for the right tool to achieve that goal. I disagree with that assumption. Most of the times you don't know that you want a specific functionality until the technology comes that implements it. Then you realize that you wanted it 'all along.' You are shaped by your environment more than you shape it.

Your time is indeed better spent doing things other than upgrading, the reason being that the software business just hasn't been able to keep up with the advances in hardware. Even though we have so much computational power available to us, we still haven't learned how to handle complexity and make more interesting, flexible interfaces. There can be innovation in document publishing software, even though we haven't seen any for such a long time. And when that innovation comes, I'm sure you will start wanting features from your word processor that you couldn't even imagine were possible.
