When it became just as inexpensive to have a cell phone as a house phone, I ditched the land line completely. It turns out that some colleges and businesses are doing the same. Some schools are pulling land lines out of the dorms, essentially requiring students to have cells.
This isn't always a good idea, of course. In an emergency, cell phones can be knocked out, and let's not forget simple things like not being able to recharge your phone if the power goes out. Land lines are far more durable than cell phones.
But for the 99.99% of the time that isn't an emergency, cell phones are fine. Just don't flip out during that .01% of the time. You'll probably have bigger issues to think about, anyway.
