I’ve noticed this too. Gordon Bell, Wes Clark, and Alan Kay have all been on record saying that they considered the LINC the first personal computer, as it was also designed for use by an individual (a biomedical researcher).
Joe November’s excellent book goes into some detail on this. LINC inspired some of the creators of the Alto, both in terms of the user’s experience of controlling the entire machine, but also in some aspects of its hardware architecture.
I certainly think LINC belongs in the pre-history of the personal computer, as does Engelbart’s NLS, but I would hesitate to call it a “personal computer” for precisely the reasons you’ve outlined for the IBM 610, which is even earlier.
If one took the criteria to be that an individual had complete control over the machine while in use, then TX-0 or even Whirlwind might count as personal computers. The term begins to lack meaning at that point.

The website mentions the Bendix G-15 as another example of this (some apparently claim it as the first personal computer and it was released commercially in 1956). The issue here is that any computer an individual has complete control of regardless of its characteristics (size, intended use etc.) can become a personal computer in terms of how that user feels about it and interacts with it. So any computer can be a personal computer in that ambigious sense it seems to me. It also gets complicated because people's interactions with earlier transistor and vacuum tube machines influenced them in designing and using the microprocessor machines that are unambigiously personal computers. So there are connections that should be made that make it complicated.
