As the unit aged, more and more I would also leave the wireless on my DX disabled. I would turn it on when I needed it which, as you mention, has become more and more rare.
My real use-case for the DX was textbooks because the screen was large and it was easier to read code snippets. Back in the day I bought a lot of those from Manning or O'Reilly directly and then loaded them onto the DX via USB. Reading PDFs was nicer as well, but again, I loaded them over USB.
