In addition to carbon footprint, I think what’s more important for most end users of 13-inch laptop is battery life, which is why Apple’s M-series have gained so much market despite its poor repairability. I bought Framework 13 because it offers comparable performance, aesthetics and power efficiency to other Windows laptops, without compromising on repairability. This won’t be true anymore if Framework does not offer any Lunar Lake options.
Actually, given the modularity of Framework 13’s design, why not offering both Lunar Lake and Arrow Lake-H to users, who can choose based on their use cases? If one’s use case changes, he/she can always exchange a mainboard for either higher performance, more RAM or better power efficiency.
