Laptop recommendation?

I trashed my MacBook Pro and I want to buy another laptop. Preferably a ultrabook and a 13" screen. I am not sure about my price tag. It must be thin and light and portable, maybe with a Intel Core i5 or i7. I might be able to wait for some models to get an Fourth generation Haswell chip upgrade.

UPDATE: Will the Sony VAIO Pro 13 ok for me? Or the announced Acer Aspire S7 (with haswell) or Asus ZenBook Infinity?
