In a recent thread a lot of readers praised Open Office, the free Open Source alternative to Microsoft Office. At 193mb it's pretty big to download over the net. But it's currently available with the February 2006 edition of Computer Shopper magazine (DVD version).
I bought a copy and loaded it on this morning. There's a word processor, database and spreadsheet. So far it looks great - just like Excel!
Small point: it's rather buried away in the DVD. To install it: Toolkit-Office-Open Office-Install-Setup.exe
