@Siphonay Ubuntu does a decent job at replacing Windows. But a "clone", does not exist, as you pointed out.
You could use WPS Office to replace the Office Suite, for the most part, or just Google Docs.
For most data input jobs, Linux should just fine.
If you're a dev and don't have to worry about supporting Microsoft ecosystems, you're also fine - unless you want to build iOS apps, then, in that case, neither MS or Linux are your friends.
