No, it isn't. These kinds of devices cover a very small but very vocal component of the computer user population, mostly bloggers, writers, i.e. people who's computers don't need shit in terms of power or storage. We hear from them constantly about how tablets are ending computers, laptops are ending desktops, phones are ending computers and it's all now and previously been nonsense.

For as many tasks that newer phones could likely take on, you are not drafting graphical work on an iPad Pro, you are not building 3D models for print or media on a frickin Samsung Galaxy and you are not simulating weather patterns and doing storm calculations on a goddamn Windows Phone. The desktop PC is not going anywhere and I don't mean to sound so angry but this constant narrative that is produced by tech media AGAIN and AGAIN and AGAIN that somehow these little, for lack of a better word, toys are going to replace the actual machinery behind the products so many consume is demonstrably false and irritating to read over and over.

Laptops are more convenient than phone + monitor.
