A:Answer It can be an alternative of a laptop but more limited.
It depends on the needs. If you will need a device for watching videos/films, play video games, or using depending of what softwares, then maybe a laptop is the best option.
However, if you are looking for an electronic device for taking notes, protecting the eyes, which's battery last more than a week, and besides that can perform many actions like a laptop would do such as browsing the Internet, running Android Apps, synchronizing stuff through the cloud, typing notes, and so on, then the Note Air is the best option.
