Well, let me approach this from two different ways.
The first would be that money, technology, and the most modern software can solve all ills versus the ols school of thought that DOS, Binary, and many years of technical knowhow is the go, especially on 'older' computers.
The 'second' thought I had is that it may be a work of 'love' to keep 'older' boxes going, but much more importantly in our buisiness with older clients and even some younger clients without the resources to upgrade you simply make do with what you have.
Having said that, In a rural and mostly 'poorer' community in Australia, Comp Tech Firms charge anywhere from AUS $80 and up, whereas we are a part of the 'community' and charge only $30 an hour for IT sevices that are better and can handle problems the so called 'experts' won't or can't touch. Including removing Nortons from a 486 or Pentium I or II with 64 meg memory..and digging all remnants out of the registry, installling freeware but very adequate security programs to help those that need the most help.
Programs like SpywareGuard, SpywareBlaster, Spybot Search & Destroy, AdAware, Crapcleaner, RegEditXP, AVG7, Avast Free, AntiVir and many more.
Just our way of giving back to the community. Of course we do much higher priced consultation, Nework, Server, and Corporate and Business work.
We think rather a nice balance. But there are many ways to approach this 'subject' and follow on queries.
I personally run XP Pro, AMD Athlon 2000+, 512 meg ram and my wife (and Partner) runs much the same but with an AMD Athlon 2500+ CPU. Networked at home, wifes box is gateway on ASDL 1.5MB pipe.
