You know, Einstein wouldn't be proud of a pen that has an built-in torch. To his shock, the concept sold like hotcakes in the bus today. There's either an increased recognition among people of the need to write things in the dark, which is stupid because the bulb is embedded on the cap, and if you're writing in the dark you'd need it to be on the nib, for no one really wants to write with the light on their face, or the introduction of a revolutionary tactic by the "company ka par-chaar". Whatever it is, aunty Sharma/Chadha/Dhingra couldn't keep their hands off these 10 buck miracles (or so it seemed), and ended up easing this guy off by at least 15 pens.

Makes me wonder whether the toilet-drain-turbine idea (courtesy Varnit) might actually be a hit.
