I had the N770, the N800 and also the N900.
It’s very telling that someone at Nokia thought it’s basically like the iPhone. In fact the N800 was a thick plastic chunk with no cellular, a resistive touchscreen, and a stylus-driven GTK+ user interface. Its most popular software feature among its userbase seemed to be that you can open XTerm.
They did eventually make an iPhone competitor on this same Linux platform (the N9), but it took five years. “Competes nearly in the same arena” indeed — in the same sense that my 8-year-old daughter competes in Simone Biles’s arena because she also likes jumping and takes some gym classes.
N800 and other Open Source Software Operations' devices were not allowed to have cellular connection because of Nokia internal politics. N9 development was also hindred by the Maemo->MeeGo and the GTK->Qt transitions. And it was killed in its infancy in the Microsoft takeover.
There's no denying that Nokia screwed up but it was mostly because of stupid politics, not technology.
