NT Need Help Choosing a Camera! Sony NEX, Nikon J1?

[humpasaurus rex]

I never owned a camera and always relied on my phone's camera. Currently an iPhone 5 owner. However I made a picture book for my gf's X-Mas present and realized that the pictures were very mediocre. I plan to use it for vacations and what not, not really looking for a DSLR. I've looked at the Sony NEX series and Nikon J1, but would like some input. Thanks fam!

Sony NEX5 is what my brother has and bought it for a great price. He likes it, but wants a nicer one.
