What is the best path forward from a T420?

My beloved T420's bezels are coming apart at the hinge. This has already happened once---I glued the plastic back together---but now is a very inconvenient time for it to happen again. So I'm thinking of upgrading.

For me, the most important factors are:

Portability - I have to carry my laptop with me on a nearly daily basis.
Linux support.
A good keyboard, preferably without the numpad.
An HDMI port.
Good battery life (~5 hours with active use should be plenty but more is welcome).

I'm thinking of going with the 8th generation X1 carbon but I'd like to hear your opinion.

Another T420 could be a good choice. They are fairly easy to find cheap and they are the last generation with the 7 row keyboard and non-chipped battery, iirc.
- They are not cheap and the 7 row keyboard is quite overrated. Literally any second hand computer for the same price would outperform it in every metric. You also have the problem of choosing between a 13 year old battery or a 3rd party battery.
  
  I've been fine with 3rd party batteries, especially without the auth chip of later models. I used an x220 til it finally gave up recently, and currently use a t520 and a t530. I do prefer the 7 row keyboard though it's not a huge deal. Sure, newer laptops are faster but so what? It's extra expenditure for performance that I don't need. When I want more CPU, I use a server or cluster.
  
  Intel underwent a massive redesign of their mobile chips where something like the i5-8250U eventually met the performance of the i7-4702MQ (these are just examples from recent memory) at a fraction of the TDP. And 7th Gen U Intel had about the same single core performance so I’m not going to jerk the T480 train here. What I mean is that they used way less power and made way less heat. Benefits are fewer sweaty palms and more time away from an outlet. Yes, you may argue neither of those are important, but they are a major improvement in portability which OP mentioned.
  
  Oh hmm maybe. I will agree that the x220 battery runtime wasn't great, but it's a computer not a phone. I'm either checking an email (short runtime is fine) or e.g. hacking code all day (need ac adapter). And at least the battery is easily swappable unlike newer models with sealed batteries. But yes sure, there are good deals on t480 and even newer machines, so shop around.
