Edit: It is cool I can plug my phone or laptop into the TV with one cable, no adapters, and get some power as well. For some reason it didn't work with my Steam Deck which was strange.
Picture me in 2007. "The iPhone. Psh. Like I'm going to switch to Cingular and pay thirty dollars for a data plan!" (Keep in mind that's $47 in today's dollars!)
I would use my N800 and Bluetooth-tether to my Verizon flip phone when on the go. It was mildly useful for things like LiveJournal and I'm sure the Twitter of that time would have worked on whatever browser Maemo had. But I had to admit by 2008 that I wanted a smartphone instead of this second device with a stylus.
In those days though, browsing the web as though you were on a desktop was thought to be the goal to aspire to. Even the iPhone launched with the default behavior in Safari being showing whole desktop webpages, and you zoomed in to the parts you wanted to use. It took a year or two for people to figure out 'responsive' and within 4 years most sites were starting to be designed for small portrait screens. At that point the landscape N800 style was at a disadvantage since the mobile sites being designed to be a little leaner, were the wrong layout, but the desktop sites were pretty heavy for a mobile device to handle. And as "apps" ate the world that probably put the final nail on our little N-series.
The visual UI + code is really cool, addresses the weaknesses of both approaches.
The fact you came to a very similar solution from first principles is very interesting (assuming you didn't know about this before!)
