Like the OP, for me the tiBook was a defining moment. A unix laptop, and it also looked good? Easy, immediate purchase.

Additionally there were UNIX laptops from NatureTech

So no, "I mean, the fact that Apple shipped a Unix laptop when all the other 'super-' vendors were unable to pull it off.,, " isn't how history went.
Other vendors were already at it, while Apple was trying to make Copland work and not being so successful with A/UX.
None of your vendors were considered viable - far, far too expensive. However, Linux on x86 laptops at the time was amazing - portable Linux.
So when Apple joined that party, and made the hardware neat, it was an easy switch. Portable, PPC-based, Unix. This was a delightful moment.
Of course, I still have a Linux laptop around, and 20 years later .. I consider moving back to it, 100%. The ride has been good with Apple, but the horizon doesn't look too great ..
What Linux laptops? It hardly worked properly in most desktops.
The first laptop I managed to get Linux working at all was a Toshiba in 1999, while these systems were being sold since 1992.
For most of the 90's I was using Linux in some capacity, professionally as well as personally.
I also had a Linux laptop (Winbook, Sony, and then Sceptre..) on which I did a lot of development and for which my carefully selected hardware did in fact work, just fine - it was certainly viable as a dev platform, and for us Unix programmers at the time, a small and light Linux laptop was far more preferable to the pizzaboxes that had to be carried in the trunk .. or more, bigger iron that you would stay at the office to use, instead of having at home.
The point is Linux really did okay in the 90's, in terms of providing Unix devs a way of working away from the computer room. I think this is an underappreciated mechanism behind Linux' success over the years .. you could carry Linux with you pretty easily, but this was not the case for Solaris, Irix, etc.
tiBook was bonkers. Suddenly, I didn't really need to sit in the room, surrounded by boxes, but rather could go to the park and access the room from under a tree.
If Be had managed to capture that, I think it would have been an amazing time. Imagine if SGI had pulled off the first titanium, unibody laptop, designed specifically for 3D. Would Alien-ware?
If there had been a BeLaptop, things might have been a lot different in 2000/2001, when things started to look very, very interesting.
I mean, the fact that Apple shipped a Unix laptop when all the other 'super-' vendors were unable to pull it off.,,
