Apple’s predecessor was a company that only produced computers, but now smartphones have become its main source of revenue.

HP is the largest PC manufacturer in the world and was even quite successful in the mobile market with its old iPAQ Pocket PC products.

Dell is also a huge computer manufacturer, but their story in the mobile market is completely opposite.

Next, let’s talk about Acer, the world’s sixth largest PC company in 2015. Acer launched many Windows and Android smartphone models and even had gaming tablets in 2015, but by 2016, it was almost gone.

Sharp used to be a computer company and was also quite successful in the smartphone market in Japan and is known to the world for extremely impressive products such as the J-SH04, the first phone with a camera, or the Aquos Crystal series,

Lenovo is also a famous computer manufacturer, once making a mark in the smartphone market and even acquiring Motorola, but in recent years very few products have left a mark.

Intel and Nvidia entered the smartphone market as chip suppliers, Nvidia even had a gaming table product, but both Atom and Tegra processor chips were not successful.

Why do PC companies fail to enter the mobile market but Apple succeeds?

Similarly, Sony at that time already had a reputation with Sony Ericsson phones and Walkman music players, so the company quickly won the hearts of users when entering the smartphone market.
