The framework 13 is around a grand pre built and around 900 if you have a spare SSD and SODIMM modules laying around.

I feel like an i3 or Celeron is not really a fair comparison. The framework machines are quite powerful and they’re targeting the prosumer/workstation market.

In the case of sustainability you do not have to trash the parts on upgrade. Framework sells cases to repurpose the main board as a PC/server. You could also buy a shell and create a second laptop. When it comes to throwing out parts on repair or upgrade you are throwing out less overall.

It’s also a fairly new company so between that and the market they’re targeting the products are fairly expensive. Further down the line they could become much more affordable as the company scales. But yeah it does not sound like Framework laptops are a good fit for you right now.
