My new pc is a mobile phone
Patrick Baudisch · 2010
Neither desktop computers nor the hundred-dollar laptop are the new mass computation platform of this world - mobile phones are. 4 Billion of them. So how come we still use PCs? Mobile devices have a major limitation: mobility requires smallness. Initially, miniaturization of hardware drove miniaturization at a fast pace, but limitations are not primarily technical anymore: today, it is almost exclusively human factors. Screens need to be large enough to be seen, keyboards large enough to be typed on. These factors, however, are practically invariant.
