No, he's right. 1 out of 15 laptop fails in the first year, 1 out of 5 laptop fails before its 2nd birthday and 1 out of 3 laptop fails in 3 years. And if you have a HP laptop, you have 1 chance out of 4 it will fail in 2 years. It's not a myth. Laptops have a very poor life expectancy. I can confirm this with my experience as well.


[citation needed]

Any one person's experience is not statistically relevant. You cannot confirm anything with your experience, even if you were in an industry where you worked with a large number of laptops.

Your experience can lead to a more scientific inquiry to investigate any claim arising from personal experience.

I realise I'm being a bit pedantic, but too many people day in and day out spout similar things about how what they experience, like, prefer is somehow universal, because they are special or something. And, yes, I'd count myself among those. I try not to draw too much conclusions from my own experience, but occasionally its interesting to see some raw unscientific observations as well. Just keep in mind that its not necessarily the case. Computers, people, things, life, existence, the universe, are all complex things with lots of small interacting parts. Its really easy to screw up our understanding of everything. Brilliant people do that everyday.

Here is one citation: www.squaretrade.com/htm/pdf/SquareTrade_laptop_reliability_1109.pdf
There has been several studies about laptops failure rates. It is confirmed by my experience but I based the numbers I cited on real studies over hundreds of thousands of laptops. Google laptop failure rate for other citations if you need. They all end up with pretty similar numbers.

Thanks for the citation. It makes everything easier to examine.

For instance: the three year failure rate is not 1/3. Its 1/5. 1/10 people accidentally break their laptop.

Also, there is a bit of potential selection bias going into the study. This looks at laptops covered by a third party warranty. So, more accurately it shows that 1/5 laptops owned by people who think their laptop may fail, fail within three years. Those who don't pay for the warranty may take better care of their laptops ( Ie not storing it in a hot car, not leaving it on 24/7, not using it to level out the kitchen table, not running the battery till death for the fun of it, using an additional cooling pad ect).

Again, I really don't have a dog in this fight, we were saying that laptops break more often or something? I'm just complaining about people's throwing around antidotes and not understanding statistics. Its of minor importance in this case, but we suck just as much when it is important... like economics, politics, and health issues.
