With the quality and quantity of Open Source and/or free products out there there is very little reason to pay for software that you can otherwise get for free. Another reason to to go Open Source is portability, If you have Mac OSX, Linux, and Window running in your home you are going to have to buy the same software three times if you want it on every machine, well actually only twice since most Commercial Off The Shelf (COTS) software wasn’t designed for the Linux environment. You can find a free and/or Open Source version of almost all COTS software. In some cases you may be making a small sacrifice in some cases the software is better or as good as what you would pay for.
Desktop Publishing:
OpenOffice.org or OOo – This suite, formerly star office and owned by Sun Microsystems is the largest competitor to Microsoft Office. OpenOffice includes a full Word Processor (Writer), a Spreadsheet (Calc), a Presentation Software (Impress), a Paint Program (Draw), and a Database Program (Base). You can save these files out in both the native Open Office Format as well as the Microsoft document formats. Available for Windows, Mac OSX, and Linux
GoogleDocs, GoogleDocs is Google’s online document creation and management system. The Docs suite includes a word processor, a spreadsheet app, and a presentation applicaiton. The suite is platform independent as it resides on the web. I use it for documents I want to share as you can grant edit capabilities to other users and it maintains versioning and change information.
Image Editing and Management
The GIMP, GNU Image Manipulation Program, is by far the most powerful image editing software you can get for free, this is not Photoshop with all of the bells and whistles but it is great. It is all I use anymore considering I don’t do proffesional photography or graphics design and this isn’t to say you couldn’t use it for that. It is extermely powerful and I have barely touched the surface. Gimp is available for Windows, Linux, and Mac OSX
Picasa, Google’s photo management software is a great way to manage and upload/label your photo’s. The program also allows you to easily upload your photo’s to Picasa Web albums and provides easy image editing for common Photo related issues. Available for Windows and Linux, I think it is still beta for Mac.
DigiKam, Digikam is my preferred photo management suite. Digikam provides a lot of the same features you get with Picasa but I like the tagging features in DigiKam better and it actually stores the tags in the Exif information of the photo. That makes the tags portable, they go with the photo. Picasa stores the photos in its own database so if you choose to move your photos to another system you have to retag the photos. Available for Linux only with potential for a Windows Port in the future.
Finance Management
GNUCash, if you haven’t heard me talk about it before, you haven’ been following long enough. Stick around I will talk about it some more. GNUCash is a powerful tool for managing not only your personal finances but can also be utilized to manage your small business finances. It uses double entry book keeping to track your income and expenses as well as your investments.

Mint.com, Mint is an online tool for tracking your finances, it can also be used for budgeting and more recently tracking investments. I don’t personally use it, I hear it is quite a useful tool. It is web based and therefore platform independent.
Along the same lines as Mint you can also checkout Yodlee Money Center.
