Haha yeah! Similar story here. When I was in high school I had a Sony Ericsson W810i.

I read multiple full books, hundreds of pages long, on this tiny screen.
I still miss the auto-scrolling feature of the Palm's ereading software.
I'll bet someone must have tried something similar, earlier, using one of the little Tandy portables.
The form factor was of the Psion great and I even ended up getting the Sony Clié NX73V more or less because of that years later... Aside from the 227g weight, it was an amazing device for ebooks with an amazing 320x480 resolution...
It's funny, I use a 6" e-ink Tolino (Shine 2HD, if I recall right) for ebooks these days, but the far lower resolution LCD displays never bothered me back then... My phone today has a considerably better and larger display (Samsung AMOLED) compared to then, and yet I would prefer not to read on that; I wonder why...
Sony’s 1992 Data Discman would beat that by 6 years.
Simpler times.
