If you forgo the built-in WiFi, the ThinkPad T440p (Haswell) works fine without any blobs (speaking from experience). I think all newer gens need iGPU blobs, sadly, but I wanted to point out a viable middle ground between modern Nvidia gamerware setups and Librebooted X200s that can barely browse the web.
