Windows only: SoftMaker Office is a free, lightweight office suite consisting of two fast, simple applications. The first, TextMaker, is a Microsoft Word-compatible word processor that runs lean (using around 12MB of RAM on my system) and is surprisingly feature rich. The second, called PlanMaker, is an Excel-compatible spreadsheet app that likewise offers impressive functionality, speed, and an equally light footprint. As if all that wasn't good enough, SoftMaker Office can run off your thumb drive, so it's a no-brainer when you need to open a Word or Excel document on someone else's computer. If you need an occasional word processor or spreadsheet app but don't need all the extra bloat of Microsoft Office, OpenOffice.org, or even previously mentioned Go-oo, this one's worth a try. SoftMaker Office is a free download, Windows only. Thanks johnsmith1234!
