I have a Ryzen 7 PC at home, with a 34" ultra-wide display, running openSUSE as my main machine - it was running Windows 10 until recently. It has a Microsoft Surface Ergonomic Bluetooth keyboard and a Logitech MX Master 2S Bluetooth mouse.
I also have an HP Spectre x360 laptop (Skylake series), which still runs Windows 10, which I share with my wife. It gets started up a couple of times a month.
At work, I have a Lenovo ThinkPad T480 laptop as my main PC. I have to cover 4 sites, so having a laptop is a requirement, for when I have to visit the other sites. But it spends 95% of its time attached to a Thunderbolt dock, with 2 24" Dell monitors, a Jabra headset, Microsoft Natural 3000 keyboard and an Anker Vertical Mouse.
I don’t have a tablet, per se. I use an Amazon Fire tablet in bed as a Kindle reader (I also have a Kindle Voyager, but I read mostly German books and need to look up obscure words now and then.
Given that I am a security and privacy “nut”, ChromeOS was never a real option for me as a complete replacement. I’d like to try it, but it isn’t really an option over here - Google itself doesn’t sell any Chromebooks through their store and the normal electronics stores don’t stock them. Amazon sometimes has the odd Chromebook, but they have been way overpriced, in general. The “highlight” was the ARM based Samsung Chromebook a couple of years back for $199, I thought that was worth a try, but that cost around $699 over here, I could get a Core i3 laptop with Windows, SSD and 8GB RAM for the same price!
