Nokia N90 (2005)
The N90 was one of three handsets launched by Nokia at the glitzy Nseries intro event back in 2005. This was a massive leap forward at the time: a recognition that phones and computers were finally coalescing.
The other devices launched - the altogether less bonkers N70 and the ludicrously oversized N91 (which had a 4GB hard disk for music storage inside - yep, a mechanical hard disk, spinning platters and all) - pushed boundaries in their own ways, but the N90 was the most overtly 'converged' device, looking as it did like a camcorder with phone buttons grafted on.
It felt like the future, albeit a bit of a clunky, silly future in which phones were going to be far less ergonomic for a bit. But these Nseries devices were the precursors of the multi-purpose smartphones of today, and the N90 can rightly claim to be the grandfather of the 20MP Xperia Z1s and optical zoom-equipped Note 3s that occupy the modern tech landscape.
