>completely ignores troves of older hardware existing in people's homes that has to run browsers just as well.

The performance has gotten worse for users of a computer from 2006, but it has improved for users of ten-year old computers (since a ten-year old computer in 2012 would have been from 2002). If you assume that a computer is less likely to be used the older it gets (and that this rate is roughly stable), then I am not ignoring older hardware at all.

>although I guess it depends on the timescale and your willingness to fudge the graph to sparse data points

thus is the nature of all real-live long-term trends. If you pick a sufficiently small timeframe, they never work.

I'm not sure I follow that logic.

I'm saying that the performance of today's firefox on 2006 hardware is better than the performance of 2012's firefox on 2002 hardware. I consider that to be a better measure than to compare both releases on 2006 hardware.

Thanks, makes much more sense stated this way, I also didn't initially understand your point.

Thanks for clarifying. If you know anyone willing to donate 2002 era hardware, I'd be willing to do some tests and benchmarks.

I used a 2006 laptop until the beginning of this year and prior to that has a 2000 desktop. Can confirm.
