Do it! You won't regret it. We haven't had a land line in 10 years, and have never even missed it. Once my oldest daughter started doing playing sports in Jr. High and babysitting for my younger kids, we got her a cell phone with text block, then once she hit high school we took off the text block. Kids these days DON'T talk on the phone like we did. They only text. She uses maybe 15 minutes a month, but 1000 texts or more!
We tried Magic Jack, but did not like it since we couldn't get a local phone number. Since you are in the valley, you could easily do it. It works for 911 also.
We also cut the cable...meaning we completely dropped it as well, and only have internet service. It was a little bit hard at first, but then I discovered that most of what we liked was offered on Hulu.com or we can get it instantly through Netflix. It is so much more convenient to be able to watch what you want WHEN you want it, plus it's TONS cheaper! (and no commercials!)
