I don't know... as computers are always going to get more powerful and less expensive over time. And I am not convinced that there is a decline in built quality either. As laptops have also improved over the years too. Like getting rid of florescent lamps and inverters and trading them for a row of bright LEDs. Which are much more reliable and not as sensitive to shock. Speaking about not sensitive to shock, we are only a few years away from SSDs replacing old mechanical hard drives. I too also believe this is far better than the older method. And speaking of mechanical hard drives, these too have been improved over the years. Some even sport anti-shock features. They have also increased in capacity and also dropped in price. Take my old Epson PX-8 built back in 1984. I like to think of it as the first netbook. As it is about the same size and shape. But the display is terrible and it is heavy. Besides it is very limited compared to today's standards. Although it is well built, nonetheless. Although it also cost $2000 (including the RAMDrive and extras) back then. I do love the Epson's keyboard, but for that price you should get a great keyboard. Even then and now though, I would have traded it for one of today's netbooks in a heartbeat. ;-) -- Bill Asus EEE PC 701G4 ~ 2GB RAM ~ 16GB-SDHC Windows XP SP2

They don't build them like they used to. It's only partly cost related, the pressure to make things smaller and lighter (and, especially, thinner) also contributes. The circuitry, the ICs and other components, are not the problem. It's the overall mechanical assembly, everything from the thickness of the motherboard and the thickness of the foil traces to the all-plastic (thin, cheap plastic) cases. The build quality is not what it used to be. Again, the problem is not the components (which includes the hard drives), it's how those components are assembled.

Well I have been taking them apart for the past 15 years. And yes, I have seen what you are talking about. Although not everything has gone that way. For example, Asus President didn't want the EeePCs to have that cheap feeling. So they made sure it had great solid lid hinges. And that was a weak point of laptops even some 15 years ago. Another trick Asus did to save on weight was to use the keyboard as a heatsink. As why add a heatsink when the keyboard would work too? I believe this was another great idea. Although the PCB are indeed very thin. -- Bill Asus EEE PC 701G4 ~ 2GB RAM ~ 16GB-SDHC Windows XP SP2

But not everything was too rosy back then either. As what about the old Toshiba 1950CS 486 laptops built in '94? Toshiba didn't have fans in them yet and in a few years the power regulators cooked themselves to death. Or what about my Toshiba 2595XDVD laptops ('99 era)? Both of them would just suddenly freeze up about twice a week. I would lose all of my unsaved work. That was really annoying as I killed power and rebooted. Even Linux users complained about it. So it wasn't Windows. Years later I discovered all one has to do to unlock the computer was to hit the Function key. Boy I wish I had known that years earlier. :-( -- Bill Asus EEE PC 701G4 ~ 2GB RAM ~ 16GB-SDHC Windows XP SP2
From: Barry Watzman on 2 Nov 2009 19:54 You touched on a couple of things that I've noticed, as I also work mostly on Toshiba (followed by Dell, Gateway and Lenovo). Actually, I had more problems with AC adapter sockets on motherboards themselves back in the old ("Toshiba built") days. That is the one -- the ONLY -- area where I think things got better (almost all later Toshibas mount the DC input jack on the case rather than the motherboard and have a short cable to the motherboard). The sockets still fail, which is a user error (mechanical stress), but now you can replace the socket without having to replace the motherboard (or remove and replace a component soldered to the motherboard). However, I've seen a HUGE number of motherboard failures in Toshiba units that I didn't used to see. Apparently (because I don't do this work myself, but I talk to the people I send motherboards out to) the motherboards themselves are now so thin and flexible that the BGA soldering of the chipsets to the motherboard fails. And I see a LOT more problems with Toshiba units in this regard than with some other brands (the A105 and A135 were particularly bad ... a huge number of motherboard failures). Another big issue -- and one that is pushing me away from Toshiba, frankly -- is problems caused by overheating. The same guys who replace BGA chipsets on motherboards tell me that occasionally they can just "reflow" the chipset and it fixes the BGA connections. BUT, too often, the chipset itself is fried by overheating. The chipsets have heatsinks also, in most modern laptops. But when the cooling system fails (e.g. the fan and heatsink become clogged with dirt, dust and hair), the CPUs handle it relatively gracefully (they "throttle" themselves and prevent their own destruction) but the chipsets don't handle it so well and are often destroyed. Not a huge difference between Toshiba and other brands in that regard, EXCEPT .... Dell and Lenovo and even Gateway provide a door (removeable panel) on the bottom of the laptop explicitly for cleaning the CPU cooling system (heatsink and fan). Toshiba used to do that in some older models (the A40's, for example), but in the newer units (again, starting, it seems, with the A100/105 series) they don't. THERE IS NO WAY TO CLEAN THE CPU HEATSINK AND FAN, other than a total disassembly of the unit (remove the motherboard from the case, because the CPU is now on the bottom of the motherboard in most units). Of course, this never happens, and we have, again, a huge number of motherboard failures. [When I do disassemble a unit, it's not unusual to find a couple of CUBIC INCHES of "hairball", often so bad that the fan blades no longer are even capable of turning.] What's sad is that this stuff is just plain dumb. There is no reason for it, it doesn't really save anything, but "that's the way they are". For no apparent reason. me/2 wrote: > > I'll have to agree with you there.
