I don't believe that. 10 - 15 years ago, many major components in consumer-grade computers had an anticipated life of 100,000 - 250,000 hours. The new standard for consumer grade stuff is 400,000 to 600,000 hours. For prof-business machines it's 1,200,000 hours. Right now, the cheapest 2.5" laptop hard-drives have a rated service life of 30,000 hours. Note also that hours is not the only measure of expected life. Since some homeowner machines get shut off and on a lot, many hard-drives are also rated in cycles of "ons" and "offs. " Cheap ones are usually rated for 50,000 cycles.
Optical drives are getting better also. I burn a lot of DVDs. I used to get maybe 500 burns to a drive and then it would start having intermittent problems. The service life seems to have almost doubled and I'm only paying around $14 each for brand new drives.
I find the newer components lasting a lot longer then they did not too long ago. If anyone is scrapping their supposedly failed 2 year-old computers - send them to my way.
