Which is fine. But what Sild says below sums it up for me.
Superman. What, are you kidding? Obviously Superman.
Anyway, there is a point to tech arguments and this thread.
Cyberpunk is a believable-science type world. It's really easy to go over to teleporters and phasers and other high-science gadgets.
But if you do that, you lose the nearness feeling Cyberpunk should get you. That it could happen tomorrow or next week, if you squint your eyes a little.
That's why most Cyberpunk fiction tries to keep it "real"-ish. Cars use gas, of a sort. Guns fire bullets. Cloaking clothes don't make you invisible, just camouflaged. Etc. Power sources should try to be plausible. Even if IRL we totally replace them in 50 years.
Oh and a big part of the reason everyone uses Dataterms in 2020? It's because they are secure.
Cyberpunk 2020 has cigarette-pack-sized cellphones, just like us. Not smartphones, although they also have paperback-book sized computers that work as phones and can even let you log-in to the virtual Net. In VR no less.
Dataterms are secure, though, unlike your pocket cellphone - and Dataterms are trusted by sellers and buyers. Cellphones sure aren't and even microPCs and decks aren't, really. Too hackable.
