Yeah. It was indeed great, I was using for 10 years, then moved to Win2003 with I still use. But I think Win2003 is even better. It have better kernel, proper SMP support (multicore), good PAE support (16GB RAM), newer drivers, etc :)
I know, there pretty nice Linux distros that are lightweight and snappy too. One day... :) but not yet :)
To be fair, I have old MacOS laptops that are my wife's laptops, we keep them around because they still turn on, and they have all her old files (I've backed it all up several different ways for her), but I never go on the web with any of the browsers installed on those systems.
