I still run SpamAssissin on my own mail server, but only because I haven’t yet seen any objective measurement showing some other solution to be better.

I used to work as a Windows application developer for a while and even though Windows itself never gave me the feeling of “oh, I’d really like to have this at home too” there was the C++ debugger in Microsoft Visual Studio that I remember as being remarkably good, to this day I haven’t seen anything quite like it anywhere else.

You’re wrong.
