Speaking seriously, my desktop PC will beat up your T420. I can't imagine doing work (writing code) on laptops with their degenerate keyboards. And for the rest you have desktops.
I don't know how you inferred I have any Apple products but actually I don't and never had. I think you just have problems with logic.
Of course you can't, but a simple USB adapter will allow you to fit a proper Model M to any laptop.
Then you just need a good bag like Michael Douglas' in Falling Down to carry it around.
The Thinkpad series is know for having some of the best keyboards ever used on a laptop. Even though I prefer using my happy hacking keyboard, I'll take the Thinkpad's keyboard over pretty much anything else. It's so good that they even sell the damn keyboard as a standalone option to regular keyboard. Trackpoint and all. And yes I write code all day.
Regarding my "logic": You don't need to own an Apple to product to be a fanboy, and as such I never said that you owned any. That's all on you and your logic. I ended my post with the same type of sarcastic fanboish retort that you used at the end of yours.
