Moore's law is cpu speed. The effective speed of software roughly
halves every 18 months (java, python, XML, SOAP, etc). In other words,
the rate of hardware performance increase is almost entirely cancelled
out by the rate of growth of software inefficiency; demands expand to
fill available resources. We scrape together some new features, but
aside from specialist/scientific stuff, the actual *functional* speed
of computers does not increase much at all. If you sit down at a gnome
desktop on a modern box, it's not actually all that different in
performance or general behaviour to what'd you got on Acorn RiscOS or
OS/2 ten years ago. Openoffice Write takes about as long to load from
hard drive as Impression Style took to load from a floppy - and it
doesn't do a hell of a lot more that you're actually going to use.

This probably says something significant.

[Note that trying *modern* software on an old box, and observing how
much slower it is, just underlines my point. The comparison here is to
the software you would have run on it when the box was new].
