If I paid (say) £1000 for a laptop computer I'd expect it to last 5 years without anything more than minor problems.
Some of the problems relate to software. For example, a good laptop bought 5 years ago might have had a PII CPU, perhaps 266 MHz, with a 2.5 gig disk and maybe 32 MB of RAM, running Windows 98 or NT 4. The software on such a system, especially the OS, is now somewhat out of date. Even the application software, e.g. the browser and email client and the office package, would not be compatible with new web site and documents, and there would be none of the (much needed) Microsoft Security updates. New software (WIN2K or better and new applications) would barely fit on the 2.5 gig disk, would bust the 32 MB RAM limit and run as slow as molasses on the 266 CPU. So, all in all, a laptop, like all computers, has obsolescence built in via software progress and
Moores Law, although it may have hardware planned obsolescence as well.
The difference is that a PC from 5 years ago can be upgraded at low cost, because better/faster/bigger generic parts are cheaper now than then. Unfortunately, many parts in laptops are not generic, making them harder and much more expensive to source. Also, OS support favours modern peripherals, so you will find that new OSes may not support old devices, and manufacturers may not write their own device drivers because it costs quite a bit for that kind of low level programming. So it may not even be possible to upgrade your system.
All in all, this means that laptop computers are viewed in the industry as ephemeral products, here today and gone tomorrow and subject to constant renewal and massive depreciation. Couple that with the tendency for people to (e.g.) drive over them in jeeps while backing out of the drive, and they are a dead-loss!
It all generates quite a bit of work, and that is all very well if you are an executive with ego problems, holed up in a hotel in Iowa with a need to get email, or a salesman who needs to make a PowerPoint pitch. But for general use, laptops are a headache, and should be avoided.
Engineering on washing machines and cars, on the other hand, moves with glacial speed. Only now, “smart” manufacturers put miniature computers into them(!), and suddenly all the planned obsolescence of laptops can now be applied to washing machines and cars, making them hard to fix, subject to constant renewal and massive depreciation! That is why I maintain an old washing machine with no computer and a 15 year old car. Things with no value cannot depreciate much.
It is heartening to hear from Gizmo that manufacturers are considering belt life in engine design – I guess they give with one hand, and take away with the other.
