I see Teams as a workplace that brings most productivity apps to one place. It can be an great standalone OS on a lightweight laptop (Like chromebook/ChromeOS). The idea to make Teams an TeamsOS with fast boot time and continue your work anytime anywhere powered by the cloud. It can also be an option to intergrate Office365 subscription in it. It can be a good replacments for business with Thinpc that uses only Word, Skype, Excel etc.
