Depends how far are you from the Apple store, you could simply replace computers as long as you are not happy, practically forever (return/replacement within 2 weeks, no questions asked).
It would be changing game switch for you - laptop to large screen all-in-one - so my advice is: think.

See that's kind of my number one problem in this situation. The closest store to me is just short of 2 hours away. Ironically, there is one in 3 different direction too! ALL of them 2+ hours away. Makes me sad, /sad face.
