The spreadsheet, KSpread, will create formulas, autosum rows and columns, graphs, and more. KOffice shows great promise, but isn't fully functional. While usable in a basic sense, not all the functions work, it crashes a lot, and has trouble importing and exporting other documents. I was easily able to import Word documents, but I found that tables don't show up correctly. I couldn't save Microsoft Word documents or open Excel spreadsheets.
More work needs to happen before it is ready for normal use.
In the meantime I recommend using one of the standard Linux office suites, either WordPerfect Office, StarOffice, or ApplixWare Office. Summary KDE 2 has some great features that make it a compelling switch from KDE 1. It has a nice clean interface and is easily customizable. Next month I will review many other windowing environments for Linux. Enlightenment, Window Maker, XFCE, and others deserve a look.
