If you are an information technology software engineering professional, it is inevitable that you will need to refresh your development hardware every few years (3-5, depending on workloads, projects, etc). Depending on your setup and configuration, the environments that you use, you could end up spending a considerable amount of time re-configuring your environment when you update your system with a newer model. One of the primary reasons is that it is almost always recommended that new computer systems be wiped (in the case of Windows machines, to reduce bundled bloatware) and re-installed from scratch and then any documents and settings migrated from the old installation to the new. Any software licences you use would also have to be re-installed. This all adds up to time that you could spend working on other tasks or doing client work.
