I'm working on a modification for a different product with a trackball, but learned about the trackpoint as well. The patent recently expired and besides that, it's ~$10-20 to buy a trackpoint component and you could hack it into a keyboard if you had the time and willingness.
(Though I just now realized that this is running Zephyr firmware, so I'm thinking maybe it might be worth retraining my emacs pinky...)
Historically the backspace key is literally that, moving the typewriter's carriage back (when the space key moves it forward).
On current computers the space key now inserts a "space" character instead of simply moving the cursor a step right.
Backspace isn't symmetric to that anymore, as it doesn't even insert a space back but deletes backwards, so it is (pedantically) a misnomer.
And this is true for "modern" computers, older ones were closer to teletypes and would move back for overwrite (e.g try vi compat mode).
But I couldn't deal without the trackpoint, which I use regularly for simple mouse actions even when I have a mouse just inches away. Also my right pinky actuates the emacs "meta" key using the key immediately below "/" (it's the RCtrl on the Lenovo), and on the Altar I that key is offset from the row above, which would be a muscle memory collision[1]. And there are no volume control keys mapped, which I find I use very regularly in the post-pandemic world of constant online meetings. (But it does have display backlight buttons? Why?! You don't use external keyboards with laptops. Seems like a weird choice.)
(Also, a nitpick: the backspace key on the US layout is marked "del" on the keycap. I REALLY hope this is a typo and that the key doesn't send Delete instead of BS when pressed!)
Beyond that though, this really does look great, and if I wasn't wedded to the thinkpad keyboard I'd definitely consider it. But... I'm a really small market, and even I'm not quite onboard.
[1] And this is the primary reason why I've stuck with Thinkpads for more than a decade. This isn't a standard key position, but Thinkpads (not even Lenovo generically, most of their other keyboards mess this up) do it best for what I want.
