Here at Hardcore Games, Apple hardware is in abundance.
The MacBook is based in an Intel Broadview CPU with 8GB RAM and a 256GB SSD. Machine runs OS X but I have seen some running Windows on them.
The iPad Pro 12.9 has 256GB has enough storage for every ebook on the planet. EPUB is half the size of PDF but the Books app can display them both fine.
The iPhone has become the basic business line. Presently the iPhone 7 plus 128GB is in use and it has survived fine with a silicon protector.
The Apple Watch Series 6: Nike has been convenient as a mobile payment device. The watch also tracks activity which appears in the Health app.
