Hmm, let's see, my father-in-law has my old dual 266 PII still in use since 1997 (coming up on 7 years in September), nary a problem. For the longest time the only update was a $40 video card a couple of years ago to replace the voodoo rush it had when it was built so it could play the latest Links. We just updated it's 4x CD drive to a DVD burner and firewire card so Mom could do back ups and play with her digital video camera.
I added a linksys wireless networking card to my Mom's Pentium 1 133mhz laptop from 1995 (8 or 9 years), no other changes, and it's still in use for wireless web browsing, document editing, etc. She still uses it for everything expect TurboTax this year which wouldn't install because it only had 32meg of memory. BTW, for those that try to tell you windows needs an reinstall every six months, this hasn't been reinstalled since it was upgraded to win98.
I think the whole Macs last longer than PCs is a myth or misconception among many Mac users, for the basics, you really haven't needed an update since the mid nineties and most of the components these days between the two systems are the same. Yes, the real tech heads or FPS junkies might be replacing their PCs more often, but they do it because it's so cheap and you can always find a home for an old machine. I haven't lost a PC since the 386 days when I overclocked and burned out a 386-25. Everything since the Pentium 1 level was either sold or donated to family and is still in use with someone I know. The 486-100 was passed on to a third party and may or may not be still in use, I lost track.
Actually I haven't even seen the gamer junkies doing much upgrading lately (guess that's why the PC industry is having so many problems), most of my gamer friends are still running on ~2 year old P4s with GeForce 4 era cards. Until the Doom 3 engine games come along and really push the demands for a faster system, I don't see those guys changing machines either.
Processors, by far, are not the only component in a system. Through my experience, the old Pentium chips work very well - and even to this day, but that isn't the case with some of the older AMD K chips, and some of the newerish pentiums (600+ mhz). Also, again I should stress, that there are more components than just this chip. Most computer companies, including Dell and compaq, do not concentrate on the cooling as much in newer systems. They keep the CPU under 'reasonable' temperatures, but by no means very cool. most current cpus run probably near a temperature between ~50-60C. This isn't good, but is within operating temperatures.
Because most companies any more concentrate on making their PCs cheap and quiet, they forgot to put in a lot of more quality materials. With a CPU running at a high temperature, for a few years, it will simply blow. It won't last that long, which is why it's important to cool your CPU as much as possible.
The cheap components even extend further. I had my first PC made by a company who decided to put really cheap materials into it. What I got was a motherboard that was discontinued within a year or two, leaving me without BIOS updates that I really needed for that machine. The machine is still in use, but isn't all that good for much else than a small server.
I also got a laptop, for fairly cheap, from compaq. It cost me about 1000 for the laptop, included a battery and everything that I needed. Within 2 months, I started running into problems with the laptop. The first problem is the battery totally died, and having it inserted would cause the machine to beep (as if the CPU has blown). This machine also had a lack of cooling, and got really hot after only a short time of use. Remember, this is all happening within a short time.
I'm not going to downgrade ~x86 based systems, as I'm using one right now - but I think to say that a company such as Dell, gateway, or compaq is good is a little bit of a stretch. bousozoku made one really good point on this. If you hand pick the components and go for quality, it will cost you more than if you bought it from a company - but on the other hand it will last far more than a computer from a major company.
Remember ewinemiller, just because a computer can last years doesn't mean it will be a worthwhile machine in a few years. My laptop is no longer worthwhile, I plan to use it as maybe a backup device after my powerbook gets here. My server, which is my 233, is still in use - but after I heavily overhauled it after the screwed up job the company did originally. It still works, but is still really limited because of the bad job this company, like most companies, do on computers.
You get what you pay for, if you're willing to spend a little more on a quality company for a quality computer - it will last you much longer, and will be of much more use, in the years to come. if you buy cheap, from a cheap company for components that are most likely not going to last, then you bought a doorstop.
