I suspect that the PC was mostly made because AMD offered to let them release a fancy CPU and they wanted to make a product that would hopefully get a different audience to hear about them. Given the emphasis that it's just a PC, I wouldn't be surprised if they don't bother making new parts for it down the line unless it sells well enough that it can fund them continuing to make a PC line. Since, as they repeatedly pointed out, it's all standard connections, it's not a problem if they stop releasing new parts, unlike their other product lines.

The convertible will probably take a year or two to shake off the rough edges, same as the 13 and the 16 have/are still doing, I'm interested to see how it does down the line once it's been out for a while and they've had time to respond to user feedback.
