There is also LibreOffice (along with OpenOffice) which take care of MSWord, eXcel, PowerPoint. There is also OpenProj, ProjectLibre, and GanttProject for the MSProject replacement. @spdrun, there is going to be a mod to GIMP that will set Photoshop back on its heels. Photoshop processes images at a higher depth than 8 bit, which means less ‘banding’ in images when contrast/brightness/gamma gets changed. GIMP only works in 8 bit…. until the next update which will significantly increase the bit depth.

An there is also the Linux options which often work quite well on old machines. The ISOs can be downloaded through BitTorrent, and either burned to a CD/DVD or put on a USB drive. Some of these ISOs can be run ‘Live’ right off the CD/DVD-rom so you can see if you like how it runs (it will run slower because access is significantly slower than a hard drive), Fedora, CentOS(RedHat clone), Debian, Mint, Ubuntu for examples.

Oh yeah, there is also Hugin for creating panoramas, including photo-spheres.
