Despite your apparent smugness how much hassle with Firefox, spreadsheets, utilities, back-up, photos, games, music, and other programs do you encounter?
Currently I have zero hassle with Win 10.
I would consider changing but don't want to be a software slave, like the old days of Linux.
Sorry if I came off as "smug".
The "old days of Linux" are long gone.
I don't use Firefox. I did years ago when it was a good browser. Switched to Brave Browser. Wife uses Chromium Browser on here Linux box.
I don't do spreadsheets but wife does. Seamless coming from her Window version before she retired.
Utilities. I use the command line. Faster and easier. I don't use them very often (don't need to) but most used are apt update, apt upgrade and apt install (if I don't use the package installer). I like doing things this way as I have control of when and how updates happen.
Back ups are done automatically with a program (native) called Back in Time. Wife's computer gets backed up daily and kept for a week. Mine gets backed up weekly and kept for two weeks. My photos get backed up whenever I make a change.
Photos. Like the OP, my hobby is photography and has been since the 1960's. Which is the reason I left my beloved Window XP. I was pretty dumb in those days and didn't keep back ups. When XP took a dump, I lost about 6,000 digital and digitized photographs. I blamed XP, not myself, and moved on. I've since learned but yet to have Linux crash, fingers crossed.
Back to photos. Coming from a long history of film photography (called it quits in 2010) I only shoot JPEG. If you cannot get it right in camera, something is wrong. I do, however, use a Linux editing program called Darktable (native). It's a Linux version of Lightroom. It's only used to convert and clean up digitized film, positives and photographs.
Games? Don't play any.
Music, videos and movie streaming is done using a dedicated Linux NUC box running Debian 12. It's an intel i3 6xxx something (so it's old) with 8g of memory and a small NVME for the operating system. Movies are stored on 5tb and 2tb external HDD's. W play music and DVD's on an external drive.
You can do pretty much anything on Linux than you can do on Windows. Linux has changed immensely in the last ten years, becoming much more user friendly. It's just a different mindset.
