1. All Apple hardware products start with i, such as iPhone, iPod, iPad, and iMac.

2. The word "i" at the beginning has a historical background. In 1997, when Jobs returned to run Apple, it was the time when the Internet was booming. Internet was the hottest concept at the time, but the hottest letter at the time was not i but e: eBay, eTrade, etoys, which was the most common way of naming at the time.

3. The first product of Jobs's comeback: a computer with almost no hardware upgrades and no unique software, but a wonderful shell (jelly-like), with networking as the core selling point (there was also the hot word NC at the time). It wanted to surpass the increasingly stale atmosphere of Macintosh.

4. Jobs was the interim CEO at the time, and the abbreviation was iCEO. This is the birth of a word for Apple products.

5. The word "i" also means "I", iPhone, my mobile phone; iPad, my computer.
