It's a fair bit older than yours, but I've been so pleased with my X260. I originally got it as a side to my T480 but I find myself just taking the X260 when studying and leaving my T480 as a docked laptop because of the smaller form factor, battery life is way better (6 hours for my use) and for what I do (attending online classes, programming, and other studies) the performance is good enough (on LMDE, it probably wouldn't take Windows well anymore)
The later X series like the X280 have options for quad core processors I believe if you wanted more performance. Given I only paid $120AUD for my X260 and I like the slight chunkiness of it (feels more rugged for on the go) that the X280 lost, I'm not upgrading anytime soon.
I take it you can't run Bedrock because you're not on Windows and don't have the game on a mobile/console device?
I'm somewhat in the same boat, although I do have a Win10 VM so I'll probably just fire the game up on that. Otherwise I imagine you could use mcpelauncher on Linux if you have the game on the Play Store.
