It’s a computer. And as a device it is just fine. Not a fan of quirkiness of Mac OS. Being used to GNU/Linux environment Mac OS seems less user friendly, less finished, than Ubuntu or Mint, for example. If you’re used to Mac OS, then you’ll be right at home. If you love iPhone and are wondering if Mac OS is just as great, well, it is not. Get a Linux based computer instead. It will serve you better.
