Which all-in-one computer to buy?

Please, don't make me out to be a dumb teenager.
I'm sixteen and I know absolutely nothing about computers.

What I do with my computers:
1. Watch a lot of movies
2. Surf the net a lot.
3. Facebook.
4. Don't play any games.
5. Use the word processor.
6. Work on loads of photograph.
7. School work.

My Demand:
1. A large screen (above 20 inches), with an amazing resolution.
2. Portable.
3. Touchscreen
4. Sleek looking. (keyboard and mouse too.)
5. 1 TB storage.
6. Really fast.
7. Windows 10?
8. Web cam
9. Built in wireless networking

I really don't know anything. I don't want an imac but was looking at 'lenovo' and 'dell' the other day. Money is not an issue but keeping it under $1000 would be great.
Any help would be kindly appreciated.
Thanks in Advance.

Added (1). With an intel chip too.

Alienware

Anything with a 20" screen isn't exactly "portable"…
That said, the Sony Tap 21 meets most all of your requirements and can be found for 750USD (the screen is 1080p, which isn't exactly "high res")
Note that Windows 8 and Windows 8.1 can be upgraded to windows 10 for free

On a side note: Personally, I would prefer something more portable like a Surface Pro 3rd gen

Anything by Dell or Lenovo r HP will be good.
