One of the things about going back into the Axis of Time series is the frustrating delight of contemplating all the technologies I missed. We didn't get fusion stacks. Instead of Posh we got Siri and Alexa. We did get flexipads, but we got them in the form of mobile phones.
Still, I don't see any point in slavishly adhering to the canon. So in Cairo we read a lot of detail about the mil-grade cell phones being used by Harry, Julia and Viv. I'm not sure flexipads are mentioned, and I'm certain that data slates are not. Nobody has complained yet.
So one of the things I'm enjoying as I return to the series is finding stuff that I can sneak in under the retcon radar. This bio-gel refrigerator concept for Electrolux, by Russian designer Yuriy Dmitriev is a great example.
Bio gel technology gets a few mentions throughout the original novels, enough to let me get away with putting something like this in the later books. Of course you can't build something like this with 1950s augmented technology – or at least I don't I think you can – but the nice thing about well-made refrigerators is that they run for years. And this bad boy doesn't even have any moving parts to break down. I can totally see Vice President Kohlhammer having a big green beer fridge just like this in his office. He couldn't keep his Heinekens in there, though. You'd never be able to find them.
