I'm coming to New York! What should I do?

I'm planning my first trip to New York in June for 4/5 days and Im pretty sure there are a lot o New Yorkers on The Verge forums.
So..

  • Where should I look to stay?
  • What are the main things I should go and see? (if you have any tech related stuff even better!)
  • Where should I eat? (I love burgers and Tacos in particular)
  • What should I do in the evening?
  • Any other tips pointers you have?

It's my first time so I obviously want to do some of the standard touristy bits but also something that only you locals know about. Bonus points for tech related stuff because I'm into my gadgets.
