I'm actually using an Intel Core 2 Quad Q9400 machine and I don't consider it an old machine. A Pentium 4 would totally be a pretty old machine, for example. Anyway, I find this as a good practice. First, to continue using perfectly working machines, and second, to develop in machines that aren't that powerful to be more conscious about resources used by the software you make.
