It's kind of mind boggling to me that they have a tight chassis, AND it meets their buildable/ugpradeable/repairable goals, AND their backwards compatibility is reaching back five years now.

I think a number of people would have expected these to eventually require a trade-off. Especially coming from pc-building land, where we see new non-backwards-compatible CPU and RAM sockets every 6 or so years.

There's a version of this where Frame.work said, "Design tradeoffs mean the 13 Pro is a new platform that is largely not backwards compatible, but don't worry, the 13 series will still get 5+ years of support and parts" and everyone goes "Aw, well, I guess that's reasonable."

I really want to emphasize that it's looking like Framework is creating a laptop with _better_ backwards compatibility and build-ability than a desktop PC.

All this is to say that this is very very impressive!

Even more impressive than going back 5 years is going back all the way to the first version. While I'm a software engineer, I've worked in teams where we shipped hardware, and for a consumer product with lots of constraints including implicit expectations, going against the entire trend of the past 15 years and targeting a hard-to satisfy market segment, they far exceeded what I expected when they announced their first product.
