So to go down the bullet point list:

• Swappable battery: I’m going to assume its a generic battery and therefore the best possible option here since I know some (a lot of) laptops have weird proprietary batteries. Point for Thinkpad.
• Industry standard m.2: Even notebooks can do this.
• Easy keyboard replacement: This looks like a lock in? Of the laptops I’ve seen where you can swap the keyboard, which is actually quite a few but in a really dodgy looking way, the keyboards look very different from this. Point for looking WAY easier but might take it away again if this keyboard really is proprietary.
• Swappable memory: I’ll give you that many notebooks solder this in but its easy to find a regular laptop with swappable memory.
• Streamlined display repairs: Much like the keyboard this looks awesome and WAY less jank than normal way you have to do it but it also looks like a proprietary part.
• Modular cooling system: I don’t really know enough to say on this one, most laptops have a cooling system you can take out with similar form factors but I doubt they’d work well with random parts from other machines, then again I doubt this laptop would work well with random parts from other laptops either so your still probably locked into buying the correct one from ThinkPad.
• Modular ports: This is actually pretty awesome, though again where else am I even going to get these modular ports.

Ultimately its still good, the stuff that’s already common has been made way easier and some new options have opened up for repair and replacement, I can’t really blame thinkpad for being the only ones providing this hardware when they’re the only ones making a laptop that would use it in the first place, its still an ecosystem lock in to a degree though even if its not an intentional one. It would be nice to see some competition in the space.
