Chromebooks are extremely popular devices, especially in education. Many use ARM processors but more and more are using Intel processors, increasing their computing power (Acer's C720 was the first Intel powered Chromebook).
Intel's new "Easy Migration" app lets users easily transfer files from their Android, iOS, and Windows machines over to an Intel-powered Chromebook. This information goes to your Google Drive account associated with the account you are logged into the Chromebook on. Photos go to Google+ Photos, contacts go to Google Contacts and the rest of the data goes to Google Drive.
This is a nice tool for users to migrate their data to their Google account, and therefore Chromebook. Especially useful for schools going from one system to Chromebooks.
It is a one time sync and does not modify anything on your phone or PC.
