> I exactly wrote that Microsoft devices were quite bad as they came too soon. And Apple came at the right moment, when low power chips were powerful enough, touchscreens were precise enough without a pen. And device had acceptable consumption, batteries had decent capacity, lifespan.

The argument is heavily reductionist because it treats technical breakthroughs as passive market timing rather than active, high-risk engineering.

Apple did not succeed by waiting for silicon to become fast enough to brute-force a desktop UI into a handheld. Instead, they reimagined the hardware-software stack from the ground up specifically around human fingertips and GPU acceleration.

Apple incorporated a GPU to accelerate the graphics. Apple acquired Fingerworks in 2005 and built custom chips to make multitouch viable. When Blackberry engineers were in disbelief about battery life, they cracked open an iPhone and found the battery occupied nearly the entire case. Apple also invested in aggressive thermal and power co-design such as power-gating states, dynamic clocks, ambient light sensors, etc.

It's because Apple was vertically oriented, they were able to make the necessary hardware advances.
