I had one of these. I loves the submarine game that was on them.
Privacy
Everything about privacy (the confidentiality pillar of security) -- but not restricted to infosec. Offline privacy is also relevant here.
I had a Visor from Handspring. Very fond memories.
My mom had one of these! They worked really well and I'd love to have one now
@thibaultamartin The convenience which more modern devices provided was effectively a one-way street. In essence, virtually nobody wants to go back to a less-convenient way of doing things. Alas, human nature is just like that.
Standards are easy to raise, but hard to lower. That device you suggest had 2MB of RAM. Nobody can make a gadget like that any longer, feature-for-feature, because 2MB of RAM is nowhere enough now. My Raspberry Pi with 2GB - not 2MB - of RAM, is hardly sufficient to even run a web browser (the OOM daemon aggressively kills the web browser).
Even a wifi router needs 8MB of ROM at the very least least to "play ball" these days, to run #OpenWRT. More like 16MB for any degree of comfort.
