Pros:
1. "Portable, sorta"
2. Reasonably high-power
3. Has an accelerometer (as does everything else in its class)
4. "Repairable"
Cons:
1. No Hall effect sensor to detect when iron is placed in holder
2. A walled single-source garden of soldering tips that doesn't even exist yet instead of using commodity COTS parts
3. The fucking temperature control is fucking paywalled behind a proprietary USB power bank. What in the fuck? (And no, it is not possible to create an argument that will persuade me to think that this is an improvement. (Yes, I know that it can be programmed; this changes nothing.))
4. Expensive.

I'll just stick with my Pinecil iron. It gets all of these things right. If it breaks (I haven't broken a soldering iron yet in over three decades of trying), I'll fix it or buy another one.
I mean: For the $250 this iFixit product costs (including the paywalled temperature control), I will be able to buy several lifetimes of worth of Pinecil irons.
