Where 2007 fits
Why 2007 is special
It was not the first smartphone, and its contribution was a capacitive touchscreen designed for fingers rather than a stylus, plus an app store the following year. Global smartphone use went from a business niche to the majority of internet access within a decade.

In historical numeral systems
Egyptian
2 lotuses, 7 strokes
2 × 1,000 + 7 × 1 = 2,007. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 corner wedges + 3 vertical wedges (sixties place), 2 corner wedges + 7 vertical wedges (units place)
33 × 60 + 27 = 2007. Places are separated by a space on the tablet, with the higher place written first.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.
