I've a Framework 13, which I got at launch (11th Gen), and have upgraded that to 12th Gen motherboard as well as swapped the hinges and backplate for a better less wobbly display. Probably the best laptop I've ever had, but it is pricey. I'm not sure theres much cost savings with upgrading vs buying whole new laptops every 18 months, but at least I'm not throwing out material. I have the old 11th Gen motherboard in a coolermaster case with spare RAM/SSD waiting for me to get time to make it into a media server.

I then got the Framework 16 with GPU module. Upgraded the camera but no CPU/GPU upgrades thus far. Use Keyboard and Numpad for the input panel options, but I've the LED panels to swap out when showing it off. The GPU is beefy enough that I can avoid also having to pack my steam deck, but you do need the better power supply, it drains battery even when plugged in otherwise. 165Hz display is great, but I do miss the 3:2 ratio screen. My only real issue is battery life in general. You do need to get it plugged in often.

I think in hindsight I prefer the FW13, it's just so much easier to travel with and the AMD APU probably has enough GPU power to play the limited games I do so I may move back, get the new 2.8k display and AMD motherboard. I much prefer the 3:2 display.

In both cases I got the DIY edition and found cheaper sources for RAM and SSD. I have had no issues with compatibility.

I intend to stick with framework longer term though. For me the benefits outweigh the cons, and its a more fun and personal ownership experience. Experience with support was reasonable, I did have an issue with the 12th Gen board where it wouldn't power on, but a few days of back and forth with email support got it revived and I avoided having to do an RMA.

The swappable ports are a very handy feature - as well as configuring it to what I think I'll need I can carry a bunch of spares easily. One trouble is that they also work on other laptops, so I find myself loaning e.g. the HDMI port to Macbook Air users. And I sometimes don't get them back. Oh well.

I also 3D printed out the cupholder attachement, which gets a few laughs. Not sure I'd use it for real though....

I wouldn't recommend it to everyone, if you want an utterly premium experience with the best OLED displays and battery life etc theres better, but I've had a lot of value from my two, and I seem to have convinced at least one local biz to swap to them because of the ability to fix them quickly when parts break.
