I moved from an older ThinkPad to the first generation Framework. While the idea of the repairability, expansion cards etc sounded great, it simply just ran far too hot and the battery life sucked. I ended up going 180 to the other end and buying a reduced 14 inch MacBook Pro (base model) which has been the best computer I've ever owned, macOS being awful aside. It's what a laptop should be like, not worrying about chargers, it not cooking your lap, just overall a very enjoyable machine

11gen (i.e. first generation) Framework did had that issues, but that was mostly a issue of the 11gen Intel CPU being used.

It's not really much of an issue anymore with newer CPUs.

Through you won't beat M2+ Macs when it comes to battery life.
