The heatpipes are a nonissue, I mean maybe they’re going to do a surprise heel turn with this new mainboard but the laptop 13 previously got the same heatpipe upgrade and it’s completely contained to the mainboard, it’s just as modular as before and you can switch between the parts. All the same parts work, it just makes that particular mainboard more efficient at cooling. Plus the parts they added in the 13 that they’re now bringing to the 16 are backwards compatible. The new graphics cards were announced to be backwards compatible too.

Also, the laptop 16 launched with the adjustable keyboard, but it only came out a year ago so maybe you’re thinking of Youtubers comparing it to the 13.

So far Framework has a great track record of not breaking backwards compatibility.
