or just use LibreOffice
If you work in an office or for an office or are connected to an office ... let them pay for it and use the software on their systems.
It's also a great excuse to disconnect from the office anyway ... if someone calls you after hours to do work ... tell them you need to access your computer at the office and won't do the work until you get back to your desk.
Otherwise, if there is no requirement from anyone and you're just doing some word processing yourself at home or doing some basic spreadsheets ... just use Open Source Software ... there's plenty of them around.
