Yes they should
Agreed, they should.
I've mainly seen people here say Linux can't be used because of Outlook & Bluetooth support.
1) If you are really still running on-site PSTs and all that, I do think Outlook will run in Wine. But if not, indeed, stick with WIndows. I don't know AT ALL how common this is though, the only people I know using Outlook any more are using the web version of it now.
2) Bluetooth. Not sure what they were on about, I've done bluetooth tethering (slower but MUCH less power consumption that running a hotspot on the phone), and audio both to and from the computer.
The funny thing for me is when I've had people say "don't you hate when computers crash and bluescreen and (whole list of Windows-specific problems)?" I point out "No, those are not computer problems they are Windows problems, run Linux or even Mac and you won't have those problems."
I think the best decision I made was to tell people plainly "No, I'm not going to fix your Windows system. No I'm not reinstalling Windows for you. No, I'm not pirating a copy of WIndows since you don't have install media. No, I'm not pirating Windows 10 (nobody wants 11...) for you. I have an Ubuntu USB stick I can install on there. No? OK then best of luck with that." (I've replaced the awful Unity desktop on my install with the gnome-session-flashback for a traditional appearance.)
