I bought a second hand Surface Pro 5 (2017), running Fedora gnome

I've started to write a review because I couldn't really find one, and most of the comments are overly positive (as it often goes on Linux forums I've come to realize). It's not done yet

But I can summarize it: as a tablet it's not great but it mostly works. It's certainly not for someone not ready to troubleshoot, and many problems have no, or no great solutions. Also gnome used with touch controls has a major bug (which, again, nobody ever mentions for some reason. It will be in my review)

As a 2 in 1 with little touch use it could be alright. The pen is quite good if you want to draw or write, even though there's a small delay. The cover is okay, but you'd be better off with a quality laptop keyboard and big trackpad

I bought it mainly for reading, mostly European format comics (bandes dessinées). The resolution is great for that, and the size is good with a reader that removes white margins

Edit: to give you an idea I bought it for 190€ two months ago, with all accessories, good condition and good battery health (which does not mean battery life is good)
