I have the Go gen 1 with 4 Gb ram, for the exact same user cases ad you described.
The compatibility with Linux is great, but be mindful that you need a Windows installation to boot from USB (!). But the pen and touchscreen works out of the box.
The performance though is not the best, boot can take some time. I'd say forget about YouTube. But light coding and non-demanding websites could work. The form factor is great though... 😊
OP, if you're interested in buying a used one, we could perhaps arrange something, if you live in Europe? Message me in that case.
PS. A Linux surface community would be great, I'd happily join it!
