The Apple ecosystem mainly. But I do really like the build quality and battery life. I can program on it, game on it (lots of retro and some modern), edit photos, run VMs. I could do all this on a PC and I have in the past. I enjoyed Thinkpads and still have the ones I owned but I don’t like the user experience when it comes to most laptops out there. Frameworks does seem pretty cool so maybe they’ll be my next laptop.
