Did you buy hardware with Linux pre-installed?
No, It’s not like there’s an abundance of options for this around. Especially if you want something with a graphics card and you want to lay hands on it first to make sure the construction isn’t shoddy. I just did a brief search for laptops with Linux on them and options were extremely limited. This is an unreasonable expectation to have as things stand.
Or is AutoCAD one of your everyday tasks?
Not every day but often. I’ve tried FreeCAD but it runs like ass on every system I’ve tried it on, and by ass I mean so slow it’s completely unusuable. I finished the entire design I was wanting to do in Fusion360 in the time it took to get a single rectangle sketched in FreeCAD last time I tried it.
We all have different definitions of “everyday”, but I haven’t had an issue web browsing on Linux in ages.
If web browsing is your only need then you can do that on a toaster. It’s not a good metric to suggest switching to Linux for most of the people looking to get off Windows. Another example of a recent problem I had was I couldn’t open pdfs off my network storage because the application didn’t understand the SMB in the path. Then there’s the fact that my secure boot enrollment randomly disappeared which somehow prevented it from booting regardless of if secureboot was on or not and I had to start from scratch with a new install just to get going again.
Possibly comes from experience with the shitty ones. I was involved in one for a now-defunct tech school I went to and all I got out of it was like $100. I didn’t have to put any time into it but that certainly didn’t make me whole.
