There was once I time when I would have agreed with the sentiment of 
getting more life out of older hardware but that time is long gone. The 
only sane way to look at that equation is by putting a value (some non-0 
value) on your own time. Once you look at this sort of thing through the 
idea that your time isn't worthless, getting more life out of older 
hardware rapidly becomes a false economy, even before you look at 
secondary benefits such as reduced heat, improved performance or more 
convenient form factors.
