I am looking to get a secondhand ThinkPad as my secondary laptop. Im currently undecided between X1 yoga g3, or x280.

I want a lightweight laptop to replace my old t440. I like yoga because it’s a convertible and this may be useful to watch movies in tent mode or use it as a tablet to browse internet. My main concern is the power button which I hear is easy to break and impossible to fix.

X280 is more lightweight and compact, but the screen resolution is lower than x1.

Both have soldered ram, so not upgradeable. I would be getting an 8GB laptop as 16gb is hard to find around here. Does cpu make a big difference? I will be installing Fedora on it.
