It's neat, but not a serious competitor to something like Framework. The MNT laptops are just cool shells around a Rock chip RK3588, which is a quad core ARM (meaning it only has two performance cores, and two efficiency cores). It's a good competitor in the Raspberry Pi world, but not a serious contender in the x86 one.

If they somehow release a modern x86 version, RIP framework. Otherwise, I don't think many existing FW customers will be switching to MNT. (Although there are a lot of other better laptops on the market they could switch to)
