1st: Have a look at cross-platform applications that are available on the current platform and Linux, and see if they are good for you (e.g. #LibreOffice, #Zotero, #Firefox, #Thunderbird, #Qoppa #PDFStudio, ...)

2nd: Is your computer/notebook and your printer etc. well supported by #Linux? Check the internet for it.

3rd: After switching: Look first for software in the distribution repositories and not on the websites of the projects. Install it from the distribution if available.
