Once in a while I wonder what people understand with an old computer. It seems some people think everything build or bought two years ago and not fast enough for the latest 3d games is an old computer that needs a lightweight Linux distribution to be useful.
Some people in different Linux discussion forums seem to think that every 32bit computer is an old computer and severely low in specifications. According to some the hardware is not fast enough if it cannot be used with every possible useless Compiz effect turned on.
I myself tend to think that an old computer is something that was build and sold at least seven to eight years ago. At the moment I have four such computers and two of them are actively used. For example, just now I write this post with an HP e-Vectra that has a 1 GHz Pentium processor and full 256 Mb of RAM. I bought it a few months ago for 50 euros that I considered an acceptable price as the computer had been upgraded with a hard disk of 250 Gb. I have been quite happy to use Vector Linux with this nice small desktop computer. Runs fast enoug for me.
On the other hand, the monitor I use is not very good. It is a 17" CRT monitor likewise by HP. I got it for free from a recycling center just like I got this nice HP keyboard. Unfortunately, the monitor must be used with maximal 100 % contrast that is the only contrast that can acceptably be read, at least when the text is black on white background.
The laptop I use for my studies is an old Macintosh iBook with 600 MHz processor and 384 Mb RAM. I got the laptop free from my father who had already two newer Macintosh laptops. I just reformatted the hard disk and installed Debian on it. Works like a charm!
I still have one Toshiba laptop with 100 MHz CPU and 40 MB RAM. I think I have Slackware 11 installed on it. For some time, I've been thinking about starting to use it again on a daily basis. I like the keyboard better than the one in iBook. And nobody would steal the laptop if I would leave it on a library desk and go to drink a cup of coffee in the café.
What is the oldest computer You still use on a daily basis? Are You happy with its performance?
