Transformer Prime, Note 10.1, or Nexus 7?

I am going to sell my iPad 2 soon, and want an Android Tablet. 187526-asus-transformer-prime_medium

The Transformer Prime has the best design and materials, and a somewhat light skin with the cool keyboard dock.


Nexus 7. Cheap and pure Google. The screen is kind of small though.


Note 10.1 It has Pen input.

What would you guys recommend?
