For email and word processing, it depends on what you've previously used. I would say that LibreOffice is quite all right for word processing. Also have a look at FreeOffice (https://www.freeoffice.com/en/) which aims for great compatibility with MS Office.
For an email client, I personally use the GMail web client nowadays, but I've used Thunderbird for a long time and it's fine (not as polished and good looking as Mail.app on MacOS though).
With competitive, affordable AMD hardware and better GPU support, both WSL and Linux (KDE Plasma) offer compelling competition.
The only rebuttal from Apple being extra padding on the UI, so it seems like I am no longer your target audience.
Fair well, it was a beautiful, cohesive experience while it lasted.
