My employer supplies me with an excellent office computer. It has a Microsoft Windows operating system, and the Microsoft Office suite with word processing, spreadsheet, presentation, database and mail programs. I have added various scientific programs for statistics and graphing, and a few programming languages for data analysis. If I were to duplicate this computing environment at home, it would cost me a small fortune. Instead, I have the equivalent functionality at no cost beyond the computer itself. I use the free Linux operating system.
So you say you have re-created the office environment at home. This is great news! It would be good to see what you use in the office and what you used as substitutes at home.
