Upgraded the monitor, 36 year payoff by saving electricity!
I put my 13 year old 15" computer monitor out to pasture when I saw a bigger LCD one for $90 on clearance. It works better and uses less electricity (20 watts versus 50 watts), but the payoff based on today's electric rates is about 36 years! Maybe if rates double, then the monitor will actually pay for itself before it dies.
I also put the 22 year old 13" analog color T.V (Samsung, Made in USA) out and went with a 19" digital LCD on sale. Energy use drops from 66 watts to 27 watts with the new T.V. and the picture is incredible with DTV over the air. Previously, we had just used the DTV converter box.
Goodwill has both units (they do work), so hopefully they will be recycled and someone will spend/save some real money by getting them for $5 or $10. I'm sure not saving any money by upgrading!
