Here is a small list of open source/free product I am using today. In some cases, a purchased product was replaced:
- FileZilla FTP Client -- This open source product replaced CuteFTP Pro
- 7-Zip Archive/Compression -- This open source product replaced PKZIP/WinZip.
- KeePass Password Safe The open source, encrypted, password manager.
- TrueCrypt Open Source Disc Encryption -- for me, it replaces PGP Desktop (though it does not offer Whole Disk Encryption).
ImgBurn is a product I have come to enjoy... Not just for DVD Video. Does a superb job of data. Because I still use Golden Hawk CDRWIN for audio, Nero is getting shoved off to the side.
Of course, I still use Firefox, and Thunderbird... I too discovered MediaMonkey and love it as well. As an iPod owner, YamiPod is nice... I use OpenOffice.org and it just gets better with each release... GOM Player is pretty cool for playing back AVI's and media files (though most of the stuff I get is jokes via e-mail)... Picasa2 and The GIMP are great photo editors.
The only thing I now use over Quicken is MoneyDance... it's not free, but can pretty much run on any platform. I have been fiddling with Linux for years and that was one of the Windows hold backs.
As a note, I make it a habit to donate to the authors of free and opensource software when it becomes useful compared to a commercial product.
