My work issued laptop is Windows 10. Hate it. Hate everything about it. I'd designed and engineered a Cloud VPN solution using Microsoft Azure and included Active Directory w/Ubuntu integration. So I can login to our brand spanking new Azure Cloud VPN implementation using my own Ubuntu desktop, authenticate with Active Direcotory and 2FA and do my work now. I use Outlook Web Access for email, O365 Web Based for work and when I have to create engineering diagrams I use Draw.IO
I'd like to send my work laptop back but they won't let me. LOL!
I agree that Ubuntu is the best supported and most reliable version available, I don't think I care that I'm not always on the latest and greatest Kernel. I'm ok being -1 on the Kernel and am willing to sacrifice for stability.
I have a Raspberry Pi 4 that I've been wanting to get Ubuntu onto. It's sitting within arms reach as I type, I'll probably get to that this week ... then I've been saying that for about a year or so now, so time to do it.
I still like having a server running on a local machine since I control it versus some mega company who may decide to shut it down.
Ubuntu on a Raspberry Pi... Everything seemed to install okay then when I tried to do a Dovecot update it failed. I didn't have time to debug it and ran out of time. I believe that it is still very new so maybe in a few months it will work. Also, the RP hardware is not the most stable -- the micro SD card. Plus the SD card has to be formatted for FAT32. Not really a problem I guess and there are work arounds. I wonder if they make a version with the flash memory soldered to the board? Anyway, the Raspberry Pi is probably more suited for the hobbyist but the possibility of being able to install a fully functional OS on a small device like it is pretty cool.
