I could go a week without TV, easy. (In fact, I'm only just now getting around to watching the stuff I recorded October 25th.)
I could go without music for a week too. It wouldn't be that hard.
My previous mobile phone I could go a week without, but I'd be hard pressed to give up my EVO for a whole week. It's not that I make many phone calls, quite the opposite. I use my EVO primarily for Internet, e-mail, Twitter and games. I use it every single day and it would be very difficult to do without it.
