I've pretty much come to the conclusion that computers (like cars) lose a significant amount of their value when you buy them new. And that what you gain on a new system considering the immediate loss of value of the system is just not worth it. That's why I buy used systems. They generally haven't lost any of the abilities that they had when they were new, and yet are no where near as expensive.
But I'm pretty sure I've spent significantly more on software over that same period. My usual practice on buying software is that I get a demo of an app and attempt to make at least the amount of money needed to buy the app within the demo period (so that the app literally pays for itself). I've done this with almost every app I own that cost me more than $100.
In some cases I look at software in the same way as hardware. Older (used) software tends to cost significantly less than new software, and it isn't like the old software has lost any functionality over time. An application from 1999 that cost $800 back then isn't going to have lost any features or abilities in the last 7 years. Yet I can get that software for under $50 today.
Operating systems are a little different as it is hard to put them into the same context as applications. And in many cases operating systems have been pretty expensive. For example NEXTSTEP was around $350 as I recall, OPENSTEP was about $400, IRIX 5.3 was about $100 and IRIX 6.2 was $280. Those operating systems would have added $1130 to my computer costs in 1998/99.
Still, considering that my income has come exclusively from computer related work since 2000 (and mainly from computer related work since 1998, though not exclusively on my own hardware or software before 2000), these expenses have been a small fraction of the return on that investment.
I guess what I'm saying is that I can hardly characterize my expenditures on computer related stuff as making me
poorer seeing as it is how I make money to begin with.
