Don't tell me i haven't done my research ..

you also need to buy controller for Xbox streaming and more...

Here is my research:

Use an Xbox Wireless Controller with Bluetooth; optionally, clip it to your phone (clip sold separately).Both Previews require this Xbox Game Streaming app, a supported Android phone or tablet (mobile data charges may apply), supported controller with Bluetooth, a Microsoft Account with Xbox profile, and high speed internet (ISP fees may apply).

Project xCloud (Preview): Project xCloud (Preview) is invite only. Initially a limited number of games will be available, with more to come over time. Access to games in Project xCloud (Preview) ends when the Preview ends. For system requirements and to sign up for a chance to join the Preview see xbox.com/gamestreaming. Invites may be sent out up to several months after registration. Registering does not guarantee you entrance in the Preview.
Xbox Console Streaming (Preview): Xbox Console Streaming (Preview) initially available to Xbox Insiders only in limited markets; availability will expand over time. Includes participating Xbox One games. Preview requires Xbox One console turned on or in Instant-on mode. Online multiplayer and some games require Xbox Live Gold, membership sold separately.

Now back to laptop part; why even bother having xbox if you have laptop. You can play any game on laptop. Why people spend money on gaming consoles? Also people can make phone calls from laptop too, why bother having phones?

One answer: convenience.
I rather have a phone that does all rather than carry 20 other equipment to do same task.
