Before I got the tablet I did everything on my iPhone. I haven't had a laptop for a few years and I don't want to sit at my desktop machine, so it had even become my normal medium for web browsing, email, etc. Now I use the phone for calls, quick texting, and in the car for navigation and music (because I have a dashboard mount and I can control it from the car stereo over USB). Everything else I do on the tablet. With a Bluetooth keyboard it has essentially become a laptop; I do document creation and editing at the coffeeshop for example. Then I take it out of the case and hold it like a book when I want to read.
Edit: I'm also finding the n7 surprisingly good for watching Netflix. I don't have cable and only have a TV in one room, and the TV just does Netflix, DVDs and video games. If I want to watch anywhere else in the house (or out of the house) the tablet is fine. The screen on the iPhone -- even the iPhone 5 -- was too small to bother. If I had thought about this I might have bought the n10 instead; it would be better. Also, it's not bad for reading comics/manga, but I'm not a fanatic about that and some people might find it too small.
