Softmaker is a proprietary rival to Microsoft Office for Linux, Windows and Android which is available as a 30 day free trial prior to purchasing, and although I mostly try out free software, the SoftMaker suite is reasonably priced for a paid app and comes in two flavours, Standard and Professional.
The standard version has 4 main functions
Daily correspondance and scientific essays, newsletters, greeting cards and more. Print or save as PDF file.
350 calculation functions,worksheets with one
million rows and professional functions such as pivot tables.
Create impressive presentations fast. Ready-made templates which
can be re-designed to do the work for you. Graphics, charts, sound,
videos, animations and slide transitions.
Add ons for Thunderbird
Takes competent care of your E-mails and ensures that you
keep your appointments, tasks and contacts under control. Manage large quantities of emails.
If you want more features go for the Professional version which comes with
four language packs and costs $30 more.
You can get a 30 day free trial and its available in rpm and deb format for Centos and Debian based distributions.
Just head over to Softmaker for more details and to download the free trial pack.
The great thing about Softmaker is that it works on Android tablets and Smartphones as well as Windows and Linux.
