Thanks for sharing. I feel that this is the point of the article too "if you don't need a high end machine...." but if you do you can't really afford to change your laptop after 10 years when most of the software won't run anymore and no securities updates are circulating for 5+ years.

I find this type of advice (change your laptop only every 10 years to save the world) irresponsible to say the least.

Imagine visiting a medical doctor with obsolte X-Ray technology, lab analysis tools etc. I wouldn't feel comfortable with that regardless of the money they saved or the illusionary "save the world" green footprint.

Of course none of this matter if one doesn't require the latest technology or software (e.g. Adobe etc.).
