Got a well specced 4th Gen i7 that does everything I need so unless it blows up, I won't be upgrading. Started working on the plan this week. Been using Mint on my secondary (non essential laptop) but never had the stones to take the plunge on my main rig.
Watching MS stepping into the enshittification trend and AI with Win11 means this is the last straw, particularly now I don't need to rely on keeping up with windows for work. Currently bashing on Linux Mint DE in a VM to test what I need and have working to be happy:
Outlook/Office - Thunderbird is good but it's been a while since I've used Libre Office but didn't have much luck with it in the past - trashing the formatting when bouncing between LO & MSO. Hoping the more recent versions are better else office web will have to do for those documents that don't play nice.
Steam - make sure I can get it going, several key games. This is the least of my worries after seeing what others have said. NVIDIA graphics may be a bit more painful.
RDP - I still have another headless win10 media box. VNC as backup. This box will be the next on the chopping block if all goes well.
Backup - this is the big one. Currently use Backblaze for unlimited backup and love the set & forget nature. No native Linux client so would require moving to their B2 platform with a third party interface - do-able, just need to get off my butt to work it out :p
File structure - always struggled with this in my playing with Linux, need to become more comfortable with where files live and general directory structure.
Will slowly pick those off over the next couple of weeks and then I should be good to go.
