You should have called this articles "20 differents tools that I use".
I personaly doesn't like all those apps.
The writer always use alternative like 7-zip for Winzip, Trilian for Messager, OpenOffice for MS Office, InkScape for Illustrator, GIMP for Photoshop, Essential for an antivirus, VCL for Media Player,...
At the end the only apps I agree with him is "Deamon Tools" since he doesn't use weird alternative.
He should have regroup apps by themes and list most of them.
