To be honest, a change of habits tends to work best. I used to think I needed a mouse to be productive, until I made the effort to learn more keyboard shortcuts for my editor. I used to think that I needed a couple of large monitors to get everything up, but realistically I was only looking at one window at a time so I went to full-screening applications into their own workspace. Basically, the less stuff you can get away with carting around, the happier you will be. The other thing: get hardware warrenties that will overnight you new parts, or get hardware that can be trivially rebought and restored to from your backups. Things go wrong, and you can’t stockpile spares, so common hardware is good hardware.
