Windows: I guess you already know GIMP, the popular open-source image editor. The good news is that now you can take GIMP anywhere with you with Portable GIMP, a special version of this powerful photo editing software that has been specifically developed to be installed and run from a removable USB memory device.
Mac: After playing around with WireTap Studio for a while I’ve found it to be an excellent application to record anything on your Mac. The program captures any hardware or software sound and includes a basic yet intuitive editor to clean up your tracks. You can save to any popular audio format and then send the track to your iPhone or iPod or share via email. Highly recommended.
Symbian: Do you ever find yourself constantly repeating things to your friends only for them to turn around and say “yeah, but you’ve told me that before”? Total Recall allows you to record mobile phone calls with the push of a button, saving them as audio files in either WAV or AMR files, so you never forget a conversation again!
